Allow customising module used for installing Puppet agent

[danielkza]

Use Case

I need to use a custom module to install puppet agents onto targets, as the operating systems I am working with don't have packages from PuppetLabs repositories at the moment.

Describe the Solution You Would Like

Allow a way to configure some module name instead of puppet_agent. It doesn't even need to change the usage, as the module can still be assumed to have a task named install.

Describe Alternatives You've Considered

I'm trying to hack around a custom way to provision the VMs created by provision, but simply pointing to a custom module would make life so much easier.

There's nothing that forces you to run the litmus:install_agent task, so roll your own 😄
I typically handle edge cases like this by replacing the rake task with a custom one. Eg, instead of calling rake litmus:install_agent, rake litmus:my_install_agent.

You could start by coping the litmus:install_agent rake task into a custom rake file.

This is an example of adding rake tasks to the litmus namespace.
