SERVER-59300 Make AsyncDBClient use OP_MSG rather than OP_QUERY for isMaster

Removing any lingering uses of OP_QUERY will be helpful in
order to eventually remove the final traces of OP_QUERY
support from the code base. Changing the AsyncDBClient to
use the "hello" command rather than "isMaster" is left as a
future improvement.
