Merge branch '20156-rescue-reference-create-due-to-file-lock-exists' into 'master'
Rescue Rugged::OSError (lock exists) when creating references.
## What does this MR do?
Rescue an exception on concurrent scenarios. I was able to create a spec for this, because if you create the lock file before trying to create the reference the reference is created without a problem and the lock file is removed. So IMHO there is a race condition where more than one process is trying to create the same reference at the same time raising the exception, so I just added the patch without specs.
```ruby
it "attempting to call keep_around when exists a lock does not fail" do
ref = repository.send(:keep_around_ref_name, sample_commit.id)
path = File.join(repository.path, ref)
lock_path = "#{path}.lock"
FileUtils.mkdir_p(path)
File.open(lock_path, 'w') { |f| f.write('') }
begin
# No exception is raised because the lock file is removed at some point in the process
repository.keep_around(sample_commit.id)
ensure
File.delete(path)
File.delete(lock_path)
end
end
```
