The current default memory cache implementation is unbounded in size and number of
objects cached. This is hardly ideal.

This PR proposes creating a TwoQueue LRU cache as the underlying cache for Gitea.
The cache is limited by the number of objects stored in the cache (rather than size)
for simplicity. The default number of objects is 50000 - which is perhaps too small
as most of our objects cached are going to be much less than 1kB.

It may be worth considering using a different LRU implementation that actively limits
sizes or avoids GC - however, this is just a beginning implementation.

* Log a warning instead of error when PR head branch deleted

* Add DefaultDeleteBranchAfterMerge to PullRequestConfig

* Add support for delete_branch_after_merge via API

If head and base repo are the same, reuse the already opened ctx.Repo.GitRepo

CleanupBranch contains too much logic that has already been performed by the Merge

* Reuse gitrepo in MergePullRequest
