(QENG-1037) Install from git should accept depth

When installing from larger repositories, being able to specify depth can cut
the time of git checkout in half. This becomes especially helpful when you are
checking out multiple repositories.
Due to the older git on some of the templates, this provides the older
--branch name --depth 1 commands, which means when using depth, one should
ensure the rev passed is a branch and not a single commit. Alternatively one
can add depth_branch => 'name' to repository and have that used instead of rev.
(QENG-967) Disable iptables on el hosts bringup.

Also fixes bug in `disable_iptables` where per-array-element was invoking wrong
method. Looks like `disable_iptables` was originally copied from
`copy_ssh_to_root`

Also adds rspec for Beaker::Hypervisor.configure

Adding a utility method for adding host entries

As much as this is a infrastructure-smell in the linux world, adding
hosts entries is still all to common in the windows world. This method
allows host entries to be configured to meet that need.

It can also be used when developing with vagrant to make sure that the
master and agent vms can see each other properly.
Enable natresolver and natdnsproxy for vagrant.

There are cases where tests run will fail when trying to download
from the outside world due to dns issues. In order to resolve this
I configured the natdnsproxy1 and natdnshostresolver1 vagrant settings

(GH-425) Sleep after killing processes

This avoids a race condition in which the killed processes haven't
exited by the time we try and unmount the root fs and the call to
container.delete errors.

(QENG-989) install_puppet_from_gem fails on Solaris

Trying to install puppet from gems would fail on both Solaris 10 and
11. Solaris 10 now has pkgutil and gem symlinked (ln -s) to /usr/bin.
Both Solaris versions have puppet-related gems symlinked to /usr/bin
after installation. This is to avoid clobbering the PATH.
