(maint) Re-Allow an array of hosts in apply_manifest_on

Before it was refactored, apply_manifest_on allowed an array of
hosts. The Puppet acceptance tests rely on this behavior, so we need
to re-introduce it.

(maint) Add new patterns to gitignore

Added new patterns to gitignore for IDEA, rbenv, and vagrant files and
folders. The tmp directory patterns were reduced from two to one.

(QA-805) Add timestamp to on(host) calls

Previously there was no timestamp, which makes it hard to correlate
beaker commands with logs on the SUT.

    /usr/bin/curl

Fix regexp for finding ip address for Fedora

The previous command for finding the IP address of a host:

	ip a | awk '/g/{print$2}'

Picks up all kinds of stray entries, on Amazon Linux for example:

	# ip a | awk '/g/{print$2}'
	109.74.196.121/24
	2a01:7e00::f03c:91ff:fe96:e1e4/64
	gre0:
	0.0.0.0
	gretap0:
	ip6gre0:

On a Fedora 20 box hosted in EC2:

	# ip a|awk '/g/{print$2}'
	lo:
	eth0:
	10.232.140.48/26

This is because its just looking for the letter 'g' which is not accurate
enough. Some interface lines have the word 'group' for example.

Changing this to the actual word 'global' seems to solve it:

	# ip a | awk '/global/{print$2}'
	109.74.196.121/24

This has been tested to work on:

* Debian 6/7
* Fedora 18, 20
* Amazon Linux
* Redhat 5/6

So I believe the behaviour should still be consistent after this change.
