Centralized Pub/Sub for microservices

I rewrote Karmen from the ground up in July 2021. It is incompatible with version 1.0.

Karmen now runs off of gRPC, which cuts down lots of nasty bugs
if: as a key under an action is now a reserved word for conditional expressions
parallel and serial blocks should perform how you expect...each block is done serially
Context variables - actions can return parameters that are injected into a block-level state. These can be referenced in conditionals with {hostname-action-variablename}
- I'll be converting the dashes to dots once I add that feature to the condition parser I used
- For each action, the {hostname-action-pass} boolean is set automatically so you can conditionally run actions based on the result of previous actions without managing a parameter. Code 200 is defined as a pass
Action error handling is improved, currently returning HTTP-like codes. I may downgrade this to a boolean
