[TRAFODION-3026] add create option storage policy
Some user want Trafodion to support HSM provided by Hadoop 2.6.0. Tables
can be stored on different type of storage hardware (SSD/HDD). Hadoop provides
HSM in HDFS, but Hbase doesn't provide the support until HBase 2.0. There is
HBASE-19858 and plan to support HSM in HBase 1.5.0. But still not released.
So before that HBase feature availible, we now use HDFS API to directly set
the storage policy on Hbase table path.
Trafodion adds new HBASE_OPTIONS to support this feature.
So when creating a Trafodion table, it is possible to specify the storage
policy (by default, HDFS provide hot/warm/cold/one_ssd/all_ssd etc)
This provide a basic support of user's requirement.
