[BLOCKED][KUDU-3342] Add an implementation of the block cache on HBW
Blocked by https://gerrit.cloudera.org/#/c/19726/
This commit adds support for a high bandwidth memory cache
based on hbwmalloc[1]. The cache is configured using
a new flag --block_cache_type=HBW.
For testing purposes, the new cache implementation wil be run on
DRAM by calling hbw_set_policy() with HBW_POLICY_PREFERRED though
there is not likely to be a performance advantage.
The code changes contained are:
* introduce the new flags to select the cache implementation
* introduce the new cache implementation, which uses hbwmalloc APIs to
allocate/free memory
* cfile-test and block_cache-test are made into value-parameterized tests
and test with all three cache types.
