Remote mirrors only get created when the URL changes, However, during the GCP
migration, the remote mirror did not get created automatically. Plus, there's
no guarantee someone restoring a repository from backup would have this
remote. We now add the remote each time we attempt to fetch from the
repository.

This works because Gitaly doesn't throw up an exception or error if the
remote already exists:
https://gitlab.com/gitlab-org/gitaly/issues/1317

In the future, we should attempt to add if the remote doesn't exist:
https://gitlab.com/gitlab-org/gitaly/issues/1316

Fix wrong commit count in push event payload

Due to a regression in !20608, the LDAP authenticator was not being used
unless OmniAuth was enabled. This change allows the LDAP provider to be used
if it is configured regardless of the OmniAuth setting.

Closes #50579

This fixes a regression in https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/20916.
We now only use the full commit count for the initial push to the default branch.
Otherwise, we rely on the number of commits that we calculated occurred in the push.

The original behavior in 11.1.4:

1. When a new branch is pushed, `@push_commits_count` was set to the total
number of refs available for the branch.
2. For other branches, `@push_commits_count` would remain `nil`.
3. `GitPushService#build_push_data` would build the push data with
`@push_commits_count`.
4. If this were `nil`, it would be set to the right value here:
https://gitlab.com/gitlab-org/gitlab-ce/blob/v11.1.4/lib/gitlab/data_builder/push.rb#L60

Broken behavior:

1. `GitPushService#push_commits_count` is always called.
2. The total number of commits is therefore always equal to the total number of refs available.
