Merge branch '40530-merge-request-generates-wrong-diff-when-branch-and-tag-have-the-same-name' into 'master'

Resolve "Merge request generates wrong diff when branch and tag have the same name"

Closes #40530

See merge request gitlab-org/gitlab-ce!15591

If a merge request was created with a branch name that also matched a tag name,
we'd generate a comparison to or from the tag respectively, rather than the
branch. Merging would still use the branch, of course.

To avoid this, ensure that when we get the branch heads, we prepend the
reference prefix for branches, which will ensure that we generate the correct
comparison.

Fix https://gitlab.com/gitlab-org/gitlab-ce/issues/40373

When copying some text from another note and paste,
it goes through `copy_as_gfm` `paste` handler
that calls `e.preventDefault()` which stops things.
But then when inserting the text, we manually trigger
an `input` event with jQuery which doesn't seem to be
picked up by Vue `v-model`.

Add controller#action metrics on Gitaly

See merge request gitlab-org/gitlab-ce!15244

At this time we had good metrics on what number or requests each GRPC
received, but were in the dark what controller#action combination was
responsable. Or if Sidekiq was responsable. Now added are call counts
per service and rpc matched with controller#action combinations.
