1. When removing projects, we can end-up leaving the +deleted
repo path dirty and not successfully removing the non-deleted
namespace (mv process is not atomic and can be killed without
fully moving the path).

2. In order to solve that, we're adding a clean-up phase on
ensure which will schedule possible staled +deleted path deletion.
Note that we don't check the current state (if there is or not a
repo) in order to schedule the deletion. That's intentional
in order to leverage Gitlab::GitalyClient::NamespaceService#remove
idempotency and ensure consistency.

Collapses directory structure in merge request tree

Closes #53069

See merge request gitlab-org/gitlab-ce!24392

During the review process for adding opentracing factories, a bug was
introduced which caused Jaeger to initialize an invalid tracer. The
bug was due to use sending nil through as a kwarg when the Jaeger
initializer used a non-nil default value.

This is fairly insidious as, the tracer looks like a tracer, but, when
methods are invoked, it throws `NoMethodError` errors. To ensure that
this issue does not happen in future, the tests have been changed to
ensure that the tracer works as expected. This could avoid problems
in future when upgrading to newer versions of Jaeger.

- #update_errored? method def is redundant, already defined from state
machine
- #update_in_progress? moved to ApplicationStatus
- #ready_status becomes a constant. Previously it was extended in ee/ so
maybe that was why it's a instance method

This change renames a dependency and fixes a minor bug, but this upgrade
is happening because Gitaly will be receiving rbtrace as a dependency.

The function that retrieves the dependable job is pretty basic and
retrieves the first job found with the matching name, but this job can
be failed but then successfully retried. In that case, we would exit the
depending job even though the dependable job actually succeeded (the
second time). Let's simplify things, be optimistic and continue with the
depending job even if the dependable job fails.

That reverts to the original behavior.
