Incorporate the "Create Service" and "Update Service" as a single "Deploy Service"

[bohdan-shulha]

From the Ptah.sh's perspective, there's just "Deploy the Service" function. We don't update or create services (however, we might want to do this on CLI).

Having Create/Update merged as a single "Deploy" we will transfer the responsibility of choosing the correct action to the actor who really knows if the service exists (and not just tries to predict, based on the logs).

Needed to simplify the implementation of this guy #136
