[devenv] Build command and data location change

Implemented the build command for the devenv script which rebuilds the docker
containers from their Dockerfile's.

Changed where the data is stored on the hosts. Moved from ./logs to ./build
[devenv] Added clean command.

The clean command stops the running containers, and removes the data directory.
Merge branch 'devenv' into develop

Added clean and build command, and changed where the data is stored on host.
