Stop vm:start when there is a problem

[poupotte]

For example, if a couchdb is started on host, vm:start log :

==> default: Clearing any previously set forwarded ports...
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 5984 is already in use
on the host machine.

To fix this, modify your current projects Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:

  config.vm.network :forwarded_port, guest: 5984, host: 1234

Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding.

After that, command continues (check status, check version, ....). Command should be stopped.
