Remove outdated code for AutoDeployBranchService
The version
method was reintroduced at some point, but never actually
used.
The gitlab_ops_client
method from BranchCreation
was only used in
one place, so we've localized it.
We've also stopped updating CI variables on production, since everything is now on ops.
987156c1 - Remove client
argument from create_branch_from_ref
This removes the need for the same argument to latest_successful_ref
,
which will remove the need for the argument from Commits.new
.
