(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

Enable natresolver and natdnsproxy for vagrant.

from the outside world due to dns issues. In order to resolve this
I configured the natdnsproxy1 and natdnshostresolver1 vagrant settings

(QENG-1212) Improve module installation experience

Prior to this puppet module installation was carried out with either
`puppet_module_install` or `copy_module_to`. This replaces them with a
method `install_dev_puppet_module` that will install either via scp or
pmt from a staging forge depending on arguements and environment

(QENG-1264) Allow users to specify recursive option for scp_{from,to}

The fix for QENG-1128 caused scp_from and scp_to to ignore the
recursive flag. This caused all scp_from operations to be recursive,
which will cause a failure if trying to copy only a single file.

The fix to this, without regressing on QENG-1128, is to actually copy
the options hash locally so that we can modify it as needed for
defaults without updating any global data.
