Review resource naming

[JimCircadian]

Noticed in the forecast-processor module that the naming is really inconsistent, with resources being suffixed either fcproc, evtproc or event-processor.

A good first issue would be to go through and ensure that the module sets the suffix consistently with a local variable: eg prefix-${var.project_name}-${local.app_name} or something like that. This would allow someone to have a good nosey through all the resources to get a feel for the code.
