[jira] [Created] (METRON-1148) Add SET and MULTISET data structures to stellar

Casey Stella created METRON-1148:
------------------------------------

             Summary: Add SET and MULTISET data structures to stellar
                 Key: METRON-1148
                 URL: https://issues.apache.org/jira/browse/METRON-1148
             Project: Metron
          Issue Type: Improvement
            Reporter: Casey Stella


With the addition of geohashes, to do analytics like tracking the statistical distribution of the distances of a user's login against the centroid of the user logins across some time, there is a need to be able to store sets (e.g. sets of geohashes) and multisets (sets with multiplicity) in a way that they can be stored by the profiler and merged across time.

This JIRA should add:
* SET_INIT
* SET_ADD
* SET_REMOVE
* SET_MERGE
* MULTISET_INIT
* MULTISET_ADD
* MULTISET_REMOVE
* MULTISET_MERGE
* MULTISET_TO_SET

These follow the pattern of the other data structures (that are not stellar language primitives)
