longer default timeout for mongodb

The default systemd TimeoutStartSec of 30 seconds isn't long enough on
slow systems.  Make it 240 seconds so we don't timeout (mainly an
issue the first time mongodb is started).

The rabbit host/hosts values were being incorrectly set, causing ceilometer to
attempt to call rabbit on the incorrect IP.

Removed standard function each

Function 'each' requires parser=future which we don't want to use

This patch replaces the class include with a custom function binding the
classes. This is the same approach as hiera_include which we used before
adding the Scenes layer.

Also changed quickstack::scene for more clarity in the output.
