running scava slaves instructions

[mhow2]

to follow up with #3 : we don't have an updated documentation section that explain how to deploy and run slaves. What we have is the older https://scava-docs.readthedocs.io/en/latest/deploy/Docker-Ossmeter/#docker-ossmeter
It needs to be tested and documented.

@MarcioMateus : thank you for having updated the documentation.
However I have a suggestion on how to runner additional workers within docker-compose : if you take a look at our docker-compose , in place of rebuilding a specific image for each slave, I'm using the original oss-app one and just tweak the arguments

Great ideia @mhow2. I will apply it to the dev branch
