Optimize method for passing variable service files

[webstergd]

Services like Yara need a rule set. Right now we have a simple script in docker that downloads the ruleset. It works but is not pretty and prone to caching errors.

I am hesitant to leave this to the Service as it could cause unnecessary data transfers.

Options:

1. Have totem fetch the files and provide them via the ram drive.
2. Identify a better method for doing this via a Dockerfile
3. Have this managed by max's upcoming addition.

Golang seems to have a potential solution via the docker file:

If we go this method, we would still need a method for having tasking specific files passed. i.e. a yara rule set. This currently done over http.
