Decide on templating language and/or implementation

Today we do not have a defined approach to how to pass templated context values into condition information fields.

Right now, this is the responsibility of the provider, but when moving to external providers, I believe that this needs to become the responsibility of the engine.

I think that for now, we can test out the functionality we do have and this will have to be part of the external provider work.

After discussion in the last community call, we decided that mustache was the correct choice for this. I am moving this out of Demo A and into Demo B for implementation.
