(Proof of concept) run commands in remote docker container to offload compute intensive commands

1. Create config-server.toml. See config-servre.toml for an example.

2. Start mandrake-server.py

3. Create Mandrake.toml file in root directory of project. See Mandrake.toml for an example.

4. Create a Dockerfile in the root directory of project to specify the environment to execute the command. See Dockerfile-example for an example.

   Remember to the working directory to /context.

5. Run mandrake-server.py <command> [arg1 [arg2 [...]]] in the project directory, where <command> and [argN] the command and its arguments to run in the docker container.

• Remove rsync dependency
• Rebuild in a less rubbish way maybe in rust also
