METRON-1148: Add SET and MULTISET data structures to stellar
## Contributor Comments
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)
You can tinker with these in the stellar REPL as manual tests.
