Add maxRefsInBatch and maxRefsToUpdate options

Processing all changes by a single run fails for projects
with the large number of changes for the following reasons:
* Large memory consumption, processing task is OOMing
* BatchRefUpdate fails (most likely, there is a limit of refs that it
  can update, could be also LOCK_FAILURE)

Added the following options:
  * maxRefsInBatch to limit size of BatchRefUpdate
  * maxRefsToUpdate to limit total number of refs, attempted by a single
  run. Since the second run on the same set of refs is a no-op, running
  multiple times with this option will eventually fix all refs of the
  project.
