(maint) formatting

This removes trailing whitespaces in install_utils.rb
(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

(QENG-1018) default dev_builds_url in Beaker needs to be updated

- update to builds.delivery.puppetlabs.net
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.
(GEM) version bump for 1.17.6 gem
(HISTORY) update history for 1.17.6 gem
Merge pull request #441 from anodelman/make-gem

create beaker 1.17.6 gem
(gh-426) Add prebuild packages to Dockerfile

Without this patch every time the specs run, prebuilt packages are
installed to the new docker image. Even when preserving the image.
To increase the speed of the test suite we install those packages when
creating the Docker image. The `HostPrebuiltSteps` checks whether those
are installed and does not do anything directly starting to execute the
specs inside the image.
(QENG-1182) Add node to classifier prior to adding pe_repo class

Prior to this commit, beaker would make the assumption that a node had
already checked into the classifier. This commit changes that by
ensuring that the node is in the classifier before giving it the pe_repo
class.

(maint) Bump version for 1.17.7 release
Merge pull request #444 from branan/ship_1_17_7

(maint) Bump version for 1.17.7 release
Add Enterprise Linux (el)
(QENG-1033) combine two conditionals into a single statement
(QENG-1186) Fix Beaker::DSL:Helpers.puppet_{user,group}

Looks like the contents of these methods were mixed upwhen originally written.
Luckily the puppet user is usually the same as the puppet group.

(QENG-797) Enhance Beaker to look for x64 installers for Windows

- add ability to install 64 bit pe builds (available for pe 3.4)
- add is_x86_64? method to host, convenience method for determining arch
  of host
(QENG-1026) Add support for x64 PE windows to Beaker

- default to installing 64 bit builds on 64 bit windows
- support install_32 host option, true = install 32 bit no matter the
  arch, false/unset = install 64 bit on 64 bit, otherwise 32 bit
