      Currently we encode an entire query filter BSON object into the plan cache key. In order to be able to map queries having a similar shape (as it's defined in SBE) we need to change the encoding scheme to take into account parameter markers, so that two queries

      {a: 10}

      and

      {a: 20}

      are mapped the same cached plan.
