Review request for hive and Paul Yang.
Summary
-------
Create a function listTableNamesByFilter that returns a list of names for
tables in a database that match a certain filter. The syntax of the filter is
similar to the one created by HIVE-1609. You can filter the table list based on
owner, retention, or table parameter key/values. The filtering takes place at
the JDO level for efficiency/speed. Added a QueryFilterType enum to easily add
new filters and separate logic for filtering.
Example filter statements include:
filterType = QueryFilterType.OWNER; filter = "owner like ".*test_user.*"
filterType = QueryFilterType.RETENTION; filter = "retention < 90 and retention
> 30"
filterType = QueryFilterType.PARAMS; filter = "numPartitions = \"2\" and
retention_days = \"30\""
The filter can currently parse string or integer values, where values
interpreted as strings must be in quotes.
This addresses bug HIVE-2226.

Added test cases to TestHiveMetaStore

> Create a function called get_table_names_by_filter that returns a list of
> table names in a database that match a certain filter. The filter should
> operate similar to the one HIVE-1609. Initially, you should be able to prune
> the table list based on owner, retention, or table parameter key/values. The
> filtering should take place at the JDO level for efficiency/speed.
