Simone Gotti 87f182a0c9 *: use errors.Is/errors.As to handle wrapped error checking
Enable golangci-lint errorlint linter to check proper use of errors.Is
and error.As instead of direct comparison or error type casting.

Simone Gotti 0e2b01a586 runservice: correctly handle skipped tasks in fetcher
skip fetching of tasks with status skipped, not only tasks marked as skip.
This avoid many wrong an noisy logs of type "executor task with id taskid
doesn't exist. This shouldn't happen. Skipping fetching"

Simone Gotti 19611c18e7 runservice: fix handling of wrong executortask status
updateRunTaskStatus should also accept transitions from not started to a
finished state like "success", "failed", "stopped" since we could miss some
status updates from the executor for many reasons.

Simone Gotti 3ac018e6e5 runservice: use all scheduled tasks in scheduleRun
rename activeExecutorTasks to scheduledExecutorTasks and don't filter out
finished tasks.
In some logic we need all the scheduled tasks and not only the not finished
ones.

Simone Gotti 145c87b4c0 runservice: minimize scheduling of tasks that will be queued by the executor
Since the executor only periodically updates its state we could end up
scheduling much more tasks than the executor ActiveTasksLimit. This will happen
in the case of many parallel tasks that can all start at the same time.

To avoid this also considere the executor tasks saved in etcd that represent
the real view of scheduled tasks.

Simone Gotti 5dd9e587fe runservice: mark not running tasks as skipped when run marked to stop
Currently when a run is marked to stop we are going to stop currently running
tasks and then their childs will be marked as skipped.

But tasks not depending on a stopped task (root task or childs with a finished
parent) that are just waiting for an executor slot, will be scheduled when
there will be a free slot also if the run is marked to stop (and then the
scheduler will stop them after some seconds).

This patch will mark all not started tasks as skipped when the run is marked to
stop.

Simone Gotti 2de91549a3 tests: improve services logging
During tests provide a zaptest Logger so all services output will be redirected
to golang testing logger.

When multiple services of the same type are provided add a unique name field to
distinguish them.

Simone Gotti 07cde065c8 runservice: use etcd mutex TryLock on fetching
When fetching avoid concurrent fetches from multiple runservices using an etcd
mutex TryLock.

Simone Gotti 5ab9f7c970 *: use etcd mutex TryLock
etcd PR 11104 (https://github.com/etcd-io/etcd/pull/11104) implemented mutex
TryLock. Since it's only available in etcd master just copy relevant code and
add a TODO to remove it when updating the etcd client to a version implementing
TryLock.

Use TryLock everywhere where it'll be useful.

Simone Gotti 72f279c4c3 *: improve error handling
* objectstorage: remove `types` package and move `ErrNotExist` in base package

* util: Rename `ErrNotFound` to `ErrNotExist`
* util: Add `IsErr*` helpers and use them in place of `errors.Is()`
* datamanager: add `ErrNoDataStatus` to report when there's not data status in ost
* runservice/common: remove `ErrNotExist` and use errors in util package

Simone Gotti 12b02143b2 runservice: don't save executor task data in etcd
Reorganize ExecutorTask to better distinguish between the task Spec and
the Status.

Split the task Spec in a sub part called ExecutorTaskSpecData that contains
tasks data that don't have to be saved in etcd because it contains data that can
be very big and can be generated starting from the run and the runconfig.

Simone Gotti bfc42ef60e runservice: fix get tasks to run
Currently `advanceRunTasks` isn't deterministic and doesn't calculate the final
state in one call. So could happen that `getTasksToRun` will select a task to be
executed since its parent are finished (marked as skipped in advanceRunTasks)
but the task isn't marked to be skipped (because advanceRunTasks has calculated
this task before its parents).

Currently fix this doing the same task selection logic done in `advanceRunTasks`
and add a TODO to make `advanceRunTasks` be deterministic by processing tasks by
their level (from level 0).

Simone Gotti c1ff28ef9f *: export clients and related types
Export clients and related packages.

The main rule is to not import internal packages from exported packages.

The gateway client and related types are totally decoupled from the gateway
service (not shared types between the client and the server).

Instead the configstore and the runservice client currently share many types
that are now exported (decoupling them will require that a lot of types must be
duplicated and the need of functions to convert between them, this will be done
in future when the APIs will be declared as stable).

Simone Gotti b81ad4cd8c runservice: fix/improve executor delete logic
* Don't fail tasks inside the delete executor action, just delete the executor
from etcd

* The scheduler, when detecting a task without a related executor will mark the
task as failed and correctly set end time of the task and its steps.

Simone Gotti 6f3798e8fe *: use sleep timer in loops
So we'll react instantly to a context cancel instead of waiting on time.Sleep
returning.

Simone Gotti 11a2ff48d6 runservice: delete executor task early
currently we are deleting the executor tasks only when all the run tasks
log/archives were fetched. But it'll better to remove a single executor task
when the task fetching is finished.

This could also fix possible issues on k8s since we are scheduling tasks but the
k8s scheduler may not schedule them if there aren't enough resources causing a
scheduling deadlock since we won't remove finished pods because their related
tasks are not removed and k8s cannot start new pods since it has no resources.

Simone Gotti 87a472aaaf runservice: add CacheGroup field to runconfig
The cache group fields defines under which cache group the run cache data will
belong. This is needed/useful for some next changes:

* Make cache correctly work for user direct runs. Since the user direct runs all
belong to the same run group (the user id) all the use direct runs will share the
same caches. To distinguish between the different caches we need to use something
in addition to the user id (the local repo uuid generated by the direct run
start command)
* Share the cache between multiple projects

Simone Gotti 9b2ce717c7 *: migrate to "golang.org/x/xerrors"
Just a raw replace of "github.com/pkg/errors".

Next steps will improve errors (like remote errors, api errors, not exist errors
etc...) to leverage its functionalities

Simone Gotti b3867fb7ca objectstorage: add posix standard storage
rename the previous posix storage to posixflat and make it currently not user
selectable (since I'm not sure it's really worth using it).

The new posix storage uses the filesystem without any escaping so it's not a
real flat namespace.

This isn't a real issue since also minio is not a flat namespace and we are so
forced to use it like a hierarchycal filesystem.

Simone Gotti bec9476d6c runservice: store related runid with logs and archives
Logs and archives can be shared by multiple runs. So removing a run doesn't
imply that we could also remote the logs and archives since they could be
"referenced" by another run.

Store also the runids as specific objects along with the logs and archives so,
we'll remove them only when no runids objects exist.

Simone Gotti 1e34dca95d runservice: split and simplify scheduler and executor naming
Also if they are logically part of the runservice the names runserviceExecutor
and runserviceScheduler are long and quite confusing for an external user

Simplify them separating both the code parts and updating the names:

runserviceScheduler -> runservice
runserviceExecutor -> executor
