EC2 and Docker don't skip

EC2 can now be used to test roles and Docker tasks that always skipped, will run now, but have an option to skip, which is used during tests.

meta fix

There was an unclosed {{ in meta/main.yml causing this error:

ERROR! Unexpected Exception, this is probably a bug: expected token 'end of print statement', got 'on'

Simpler is better

The variables are now expanded in vars/main.yml, making it easier to read and maintain.

gitignore

One for this repo, one for the instantiated.

Ready

All improvements included.

Single file variables

Instead of the many variable files in vars/, I've switched back to a simpler structure, also to be prepared for Galaxy 3.1 and it's star ratings.

Jeff Geerling

Saw a presentation of Jeff Geerling yesterday at Ansible Fest 2018 (Austin) which suggested to add:

1. purpose to the readme, what does this role do?
2. links to CI and issues.
3. description of how to test the role.

Good hints Jeff!

EOFNL

One file was missing a new line at the end of the file.

Slack

Slack notifications are now used and email notifications are disabled.

Linter

There was a linting issue in vars/CentOS.yml, causing molecule to error.
