Rename claim to instance (#547)

* Rename claim to instance

* porter bundle list -> porter instances list
* alias porter instances list to porter list
* porter bundle outputs list -> porter instance outputs list
* porter bundle outputs show -> porter instance outputs show
* Made positional argument consistent for specifying the instance name
when listing outputs for an instance. I made it a flag since outputs
show uses a flag. Positional arguments should be used when it is the
name of the resource. In this case the resource is output, so instance
should have been a flag to begin with.
* Updated documentation to match.

* More fixes
