 Description   

When creating a columnar index it should be possible to specify a projection over which fields to index, or not index.

This task is to add support for this feature on the creation side. This includes adding the field projection argument to the createIndex command, parsing/validating the projection, storing it in the catalog, and re-parsing it at startup.
