Motivation

The query and analytics services allow queries that have named and positional parameters in the same request. We should allow users to make queries with both types of parameters.

Changes

Public API:

• Update query_options & analytics_options so that setting named parameters doesn't clear any existing positional parameters and vice versa.
• Document the fact that setting positional parameters overrides existing positional parameters, and setting named parameters overrides existing named parameters.

Core API:

• Update encoding of query/analytics_query requests so both named and positional parameters are included in the payload if both have been set.
