SERVER-59512 add new, cleaner query interface to DBClientBase

The new interface uses FindCommandRequest, and avoids any
characteristics that relate specifically to the
no-longer-supported OP_QUERY wire protocol message. This
patch moves all callers of 'findOne()' onto the new API, but
more work is required to fully eliminate the old 'query()' API
from DBClientBase.
