  1. Optimize batch read and caching in compactor 

    Read cache does not cache checkpoint entries. This invalidates the
use of checkpoint batch read in stream layer. This PR adds the extra
parameter CHECKPOINT_READ_BATCH_SIZE to compactor_runner.py and set
it to 1 for compactor.

This PR also enables read cache for compactor to allow just one batch
read of non-checkpoint entries to be cached. This optimizes the read
efficiency of checkpointer.
