Implement the stx control module so that the developer could
manage the four containers with the 'stx control xxx' command.
Containers: (stx-builder|stx-pkgbuilder|stx-lat-tool|stx-repomgr)
Now we assume that we have a minikube env to be ready for this
module, we can use it directly. For the minikube env installation
we can build it with the stx-init-env script later.
Now support the action: [status|start|stop|enter|upgrade]
stx control status: Check status of the containers
stx control start: Boot the containers up
stx control stop: Shutdown the containers
stx control enter: Login the container(default builder)
stx control upgrade: Upgrade the containers
This module will be used after the developer have a minikube env,
Please refer to the more help information with the command
'stx control --help'
