(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.
This should include a negative test for when `metadata.json` and `Modulefile` do not exist.
