ship init command should work for plain kubernetes yaml also

[marccampbell]

When running ship init pointing to an upstream repo that only contains kubernetes yaml (not helm), a default lifecycle should be applied.

[marccampbell]

To support this:

• ship should have a flag to specify the upstream resource type (helm, k8s, ...)

• ship could try to determine the resource type automatically

• a default lifecycle for k8s applications, different from the default lifecycle for Helm applications

• ship should have progress messages printed that communicates this information to the user, i.e.

ship.yaml not found ... determining application type [application-type] ...
Generating default ship.yaml for [application-type] application ...

where [application-type] is the resource type either provided by the flag or determined automatically (helm, k8s, etc.)

I'm going to take a stab at a POC for this
