* Remove old docker packages
This removes docker packages that are obsolete if docker-ce packages are to be installed, which fixes some package conflict issues that can occur during upgrades.
* Add support for setting obsoletes=0 when installing docker with yum
* Adding yaml linter to ci check
* Minor linting fixes from yamllint
* Changing CI to install python pkgs from requirements.txt
- adding in a secondary requirements.txt for tests
- moving yamllint to tests requirements
- Only have ubuntu to test on
- fedora and redhat are placeholders/guesses
- the "old" package repositories seem to have the "new" CE version which is `1.13.1` based
- `docker-ce` looks like it is named as a backported `docker-engine` package in some
places
- Did not change the `defaults` version anywhere, so should work as before
- Did not point to new package repositories, as existing ones have the new packages.
The default version of Docker was switched to 1.13 in #1059. This
change also bumped ubuntu from installing docker-engine 1.13.0 to
1.13.1. This PR updates os families which had 1.13 defined, but
were using 1.13.0.
The impetus for this change is an issue running tiller 1.2.3 on
docker 1.13.0. See discussion [1][2].
