…ess (pravega#2760)

Sets several RocksDB default parameters with conservative
values to preserve memory:

- Cache block size has been set to 32KB (default 4KB) to
reduce the memory usage of internal indexes of RocksDB.
- Total space for memtables has been set to 64MB to
reduce memory usage absorbing writes (by default is
64MB per memtable).

The block cache size for reads by default is 8MB, which
has been considered small enough and has not been 
further reduced in this PR.
