Add ability to pass --target-dir to beaker-module_install_helper

[canihavethisone]

The function install_module_dependencies_on has no param to specify a target-dir when installing deps.

A subfunction of install_puppet_module_via_pmt_on has a hash merge with default_module_install_opts however I am unable to get this to work when set in spec_heler_acceptance to use resolvable params such as #{agent[0].hostname}

I actually just merged #26. Does that solve your need?

[canihavethisone]

Hi, thanks for that. I will look tonight however am unsure if the new opts you added will be available from the install_module_dependencies_on function?

[ekohl]

Ah right, I only added it to install_module(_on). You would need to expand the API for install_module_dependencies(_on) in the same way.

yes, any help getting this code added would be awesome. :)
