Feature Request: Support REDIS for Mutex and locks in ST workflows

[cydergoth]

It would be good to be able to be able to provide mutual exclusion for workflows which need to do a read-modify-write on a resource which could potentially be involved in a race condition between multiple workflows. Redis, as an existing part of ST2, seems like a possible solution

Hey @cydergoth, this seems like a good idea to discuss on. I however think this might be the wrong repo for it (this is for the redis StackStorm integration pack on the StackStorm Exchange. Note that this isn't the same as the redis used for coordination in st2.

I think you should move this to https://github.com/StackStorm/st2/issues or https://github.com/StackStorm/st2/discussions

Well, I want to use it inside workflows, so I need a callable action.
