Fix bugs on proxy/handler after changing CreateProcesses/CreateDockerContainers signature.
All tests uses CHILLAX_ENV “test”.
Add basic tests for storage.
Make sure backend/processes errors slice is empty when there are no errors.

StopProcesses should not block.

Checks backend.Process.Instances in test.
ProcessWrapper is able to check if process still exists.
StopProcesses is no longer async.

proxy/handler also watch docker containers when starting it.
MuxFactory params changed. Fixed it.

Small cleanup to actually use the abstractions on /proxy/backend_docker
Fix server_test
CreateContainers makes sure numprocs is respected.

proxy/backend is able to inspect and start multiple containers.
