In WebIDE, when closing a file, switch to the new one before closing the active one

See merge request gitlab-org/gitlab!51483

To avoid disposing the repo_editor component, we have to
make sure we always have an active file if we have any
open files at all. Othewrwise the whole component gets
diposed that triggers all possible events and unnecessary
processing related to diposing the old one and setting up
the new editor instance

Adding benefits of feature flags section

See merge request gitlab-org/gitlab!49962

- On the feature flags process page there were a lot of examples of the
  cost of feature flags, but it the reasons we want to use feature flags
were not clearly spelt out. This change adds a section about the
benefits of using development type feature flags.

These workers should have the code_testing feature category.

Add /-/metrics/system endpoint

See merge request gitlab-org/gitlab!51095

While we do publish VM metrics such as GC stats
into Prometheus already, due to sampling and
collecting randomness these are difficult to
use in performance measurements.

Having an endpoint export VM stats directly
from a warm process adds accuracy. It also
allows us to stabilize results e.g. by running
a full GC collection prior to rendering stats.
