Deploy to OpenShift command

Uses the existing menu to select which Quarkus project to deploy.
Uses OpenShift Connector in order to deploy the Quarkus project to
OpenShift.
The component is created if it does not exist yet (i.e. no .odo folder
is present), and it's pushed if it already exists.
OpenShift Connector handles selecting/creating the application and
naming the component.

Closes redhat-developer#313
