Add initial ubuntu 18.04 support

[jkroepke]

Ubuntu 18.04 ships 7.2 by default.

https://packages.ubuntu.com/bionic/php

@jkroepke thanks for the PR! Can you add both distributions to the metadata.json? We need to make sure that facterdb has mocked facts before we merge this. Can you take a look at the failing spec tests?

17.10 and 18.04 are currently missing: https://github.com/camptocamp/facterdb/tree/master/facts/2.5

Like #429 (comment)

only the Debian 8 Test are failing.

Since 18.04 isn't released at this moment (and the puppet spec test infrastructure not ready for 18.04 yet) I suggest to not add the 18.04 release to the supported os.

I starting with 18.04 yesterday to prepare my code for bionic. I required some puppet workarounds because puppet itself isn't 18.04 ready. Thats why I'm calling this initial support.

See: puppetlabs/puppet#6706

ugh debian...

We can't merge this before facterdb is updated and Ubuntu 18.04 is released, but the change to metadata.json is required.

Whats the status of the PR?

About the failing test, see #430

@jkroepke currently i have a little lack of time for fixing the debian tests, which block quite all PR

see #433 (comment)

Hey @jkroepke, could you please rebase?

[jkroepke]
