ENT-3764: Change comments to follow Conscious language initiative

Card ID: ENT-3764

This is part of Conscious language initiative changes.

Following changes were made:
- master -> main, root
- blacklist -> blocklist

Words that were not replaced:
- subscription-manager.spec: This file contains changelog which is not
  subject to these changes.
- pylintrc: 'MASTER' is required INI heading.
- docs/sphinx/conf.py: 'master_doc' variable has been renamed to
  'root_doc' in Sphinx 4.0 (May 2021). 'master_doc' is still an alias.
  Not changed because test-requirements.txt still specify Sphinx>=1.8.5
  for Python 3.
- src/dnf-plugins/product-id/README.md: Primary branches of linked
  projects are called 'master'.
- test/manifestdata.py, test/test_cert_sorter.py,
  test/rhsmlib/test_attach.py: 'master' is a value of
  'subscriptionSubKey' returned as 'pool' attribute from Candlepin
  server.
