Replace bash scripts with docker-compose

[mmatczuk]

The idea is to remove all the bash files and replace them by a docker compose file. The variables should be put to .env file (auto read by docker-compose) other things can be directly rewritten do docker-compose file.

Benefits:

• more standard, easier to read, port or include in an containerized environment
• single control point (docker-compose)
• more control
• easier to use

Make sense @rusher81572 already made a similar effort in scylla-code-example
Even with a small bash wrapper, it should still simplify the stack.
