Using configparser / typing only on applicable Python versions
Using configparser / typing only on applicable Python versions

Details:

* The configparser package is a backport of functionality from Python 3.2
  to older versions. However, the minimum-constraints.txt file pulled it
  in unconditionally. This change pulls it in only for Python < 3.2.

* The typing package is a backport of functionality from Python 3.5
  to older versions. However, the minimum-constraints.txt file pulled it
  in unconditionally. This change pulls it in only for Python < 3.5.
