[#2969] revised the quickstart page

- added link to the cloudsmith tarball page
- added |cloudsmith_repo| substitution
- added sphinx-tabs extension
- changed yum to dnf because with the deprecation of CentOS 7, all
  remaining supported rpm distributions have dnf by default.
- changed `/path/to/your/kea6/config/file.json` to the configuration
  file installed by default `/etc/kea/kea-dhcp6.conf` for easier startup
- regenerated doc/sphinx/src/requirements.txt mainly to include
  sphinx-tabs
- added sphinx-tabs to hammer.py
