Gh-3222: Add OpenCypher translator to GafferPop

[tb06904]

This integrates the opencypher translator into GafferPop to allow passing a cypher query in a with() step. This takes the query and translates it into a Gremlin traversal to then run as normal in GafferPop. Added some limited testing to ensure it is functional but more extensive testing of the translator is already carried out in the opencypher repo.

Also fixes small bug where the limit for GetAllElements was missed on some methods in GafferPop.
