CommitValidatorCache: rename to BranchCommitValidator

Remove the commit cache, since the validator is instantiated per
branch. This means the cache can only do something useful if there are
two pushes to the same ref, eg.

  git push origin sha1-1:refs/head/master sha1-2:refs/head/master

this is not a useful-enough action to warrant the complexity of a
cache.
