ISTWCMS-4802: Do merges with repository clones instead of merge requests

See merge request !12

Merge requests will not merge for the third and subsequent tags because
the release branch is behind. GitLab requires a rebase which does not
work with our branching model. Instead, do the merge in a repository
clone.

The clones will be kept to avoid the need to clone each time. The user
running the script must have read-write access to
UW_WCMS_TOOLS_REPOSITORY_DIRECTORY and ssh keys configured to allow the
push.
