    Added microstack.remove command

    Running microstack.remove will remove the br-ex virtual bridge device,
    then uninstall MicroStack.

    We do this because we can't use ovs-ctl to remove the bridge as part
    of a remove hook, as the Open vSwitch daemons are not running at that
    point. The microstack.remove command gives operators a way to cleanly
    uninstall the snap, without needing to reboot to get rid of br-ex.

    Added test exercising the code to test_basic.py.

    Rerranged entry points a bit (moved some things into main.py) to make
    code sharing easier, and to prevent a proliferation of entry point
    scripts in our root dir.
