[SERVER-10363] User should be able to specify 2dsphere paramaters - MongoDB Jira

My database has approximately 103 million documents representing polygons in the UK.

Currently, a query for a 10x10m square can scan 500-100 rows and return 5.

I know S2-geo-lib has the potential for cells of <2cm so I believe the default values in S2IndexingParams:

maxCellsInCovering
finestIndexedLevel
coarsestIndexedLevel

are inadequate for me at the moment, and so it would be beneficial to be able to set these upon index creation.
