[dpdk-dev] [PATCH v10 11/11] doc: support python3 only

[Kevin Laatz]

Changed script to explicitly use python3 only to avoid maintaining python 2
and removed references to python 2 from the documentation.

The deprecation notice for python 2 support has been removed. A section
was added to the rel_notes for this patchset.

 * dpdk-setup.sh: This old script relies on deprecated stuff, and especially
   ``make``. Given environments are too much variables for such a simple script,
   it will be removed in DPDK 20.11.
