[VOL-5307] - bulk cleanup lintcheck errors

sphinx_conf/linkcheck_ignore.py
-------------------------------
  o Add more URL exclusions.  Was working earlier but urls created by
    sphinx template substitution are failing 'make linkcheck'.  Not just
    ONF urls, maven central, etc.

testing/voltha_test_automation.rst
----------------------------------
  o Remove stale URLs referencing deprecated views and jobs.
  o Update refrences form 2.8, 2.9 => 2.11 & 2.12.
