    Description

      Epic Summary

      Summary
      Replace dnspython with our own SRV dns implementation.

      Motivation
      mongodb+srv:// URIs require SRV dns lookups. Currently pymongo (and motor) require the dnspython library to be installed. This causes user pain because dnspython is not installed by default (see MOTOR-706 and PYTHON-2605).

      dnspython also brings its own problems as described in PYTHON-2362, PYTHON-2002, and PYTHON-2364.

      Instead we should implement the required DNS logic ourselves and drop the dnspython dependency.
