[WIP] Allow PLUGIN_META to be more easily overridden

[kbrock]

This is more of a discussion point.

Currently, we override branch/tag for each of our production branches. My goal is to be able to not change the Gemfile for our branches.

For individuals, we often need to override the git repo to point to personal branches.

Not sure the best way to implement this with externalizing it into an ENV variable.

...
This is an old local branch. I remember feeling strongly about this before but can't remember the exact reason. Think I was building an appliance or something. I want to make building a personal appliance/containers easier.

I have a bunch of scripts at release time in manageiq-release to ensure these are all updated. This would have to be taken into consideration for this change.

What problem are you trying to solve here? It seems like you want to replace the git references by setting a constant?
