This PR separates the block cache and the index cache. Earlier we had a mix of both the caches. Block Cache -> Stores block. Should be used when running badger with compression/encryption Index Cache -> Used to limit the memory used by table indices and bloom filters. This PR also remove the `KeepBlocksInCache` and `KeepBlockIndicesInCache` options. (cherry picked from commit c3b1582)

Badger now has 2 separate caches blockCache and indexCache (see dgraph-io/badger#1476) This PR adds --cache_mb and --cache_percentage flags for alpha and zero.

Cache size is in MBs and format of caches is as follows For alpha: PostingListCache,PstoreBlockCache,PstoreIndexCache,WstoreBlockCache,WstoreIndexCache For zero: blockCache,indexCache
