Add support for ansible_ssh_host (#20)
Add support for ansible_ssh_host (#20)

With the use of onion services, we have to use hosts files
like this:

    [tor_relay]
    relay_1 ansible_ssh_host=exampleexample.onion

So in order to make the automated ssh keys discovery work, we need
to use the ansible_hostname if set, not the name.

(also reindent, because flake8 was not happy)
