(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-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.
