Replace FSF for Strelka

[dcode]

Fighting the aging Python 2 dependencies of FSF has gotten a bit painful over the last several releases. I'd like to propose we move to Strelka which is published by the team at Target and very actively maintained. An additional bonus is the file submission tool is written in Go and statically compiled to run on the system submitting files without all the Python dependencies. This also makes it very well suited to run in a container environment.

It seems like it would solve those problems, although with out testing it my current opinion is that this could potentially also cause more problems in the future. To scale the tool it uses an additional tool Envoy which just adds additional tools that need to be configured and added to the ansible build scripts.
