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 72f279c4c3 *: improve error handling
* objectstorage: remove `types` package and move `ErrNotExist` in base package
* objectstorage: Implement .Is and add helper `IsErrNotExist` for `ErrNotExist`
* 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 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).

The same function is already provided by pointer.go

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 f812597410 runservice: maintenance/export/import
Implement runservice maintenance mode and export/import.

When runservice is set in maintenance mode it'll start only the maintenance and
export/import handlers.

Setting maintenance mode will set a key in etcd so all the runservice instances
will detect it and enter in maintenance mode. This is done asyncronously so it
could take some time (future improvements will add some api to show all the
runservice states)

Export is always available and will export the datamanager contents. Currently
only datamanager contents are exported (no logs and workspace archives).

Import is available only during maintenance, given a datamanager export will
import it and reset etcd to this import state.

Simone Gotti b8c2b4020a db: use context functions
Use the go sql context functions (ExecContext, QueryContext etc...)

The context is saved inside Tx so the library users should only pass it one time
to the db.Do function.

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 5e21089baa *: remove unneeded logging
remove many log.Info entries that where old debugging entries and move some of
them to the Debug level.

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 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
