Implement a new error handling library based on pkg/errors. It provides
stack saving on wrapping and exports some function to add stack saving
also to external errors.
It also implements custom zerolog error formatting without adding too
much verbosity by just printing the chain error file:line without a full
stack trace of every error.
* Add a --detailed-errors options to print error with they full chain
* Wrap all error returns. Use errors.WithStack to wrap without adding a
new messsage and error.Wrap[f] to add a message.
* Add golangci-lint wrapcheck to check that external packages errors are
wrapped. This won't check that internal packages error are wrapped.
But we want also to ensure this case so we'll have to find something
else to check also these.
* add a config option allowPrivilegedContainers
* fail task setup if privileged containers are requested but they aren't
allowed.
* report if privileged containers are allowed to the runservice
* Delete the command and it's rule in the Makefile
* Don't use it inside gitserver and remove related config option (also from
examples)
* Remove webhook parsing from agolagit gitsource
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
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
`lts` was choosen to reflect a "long term storage" but currently it's just an
object storage implementation. So use this term and "ost" as its abbreviation
(to not clash with "os").
