func describe ignores extensions on the trigger

[matzew]

Doing func subscribe for a few attributes/extensions, like:

func subscribe --filter type=com.example --filter extension=my-extension-value --source my-broker

Results in the correct trigger:

...
  spec:
    broker: my-broker
    filter:
      attributes:
        extension: my-extension-value
        type: com.example
    subscriber:
...

However, func describe is not showing the extensions:

func describe
Function name:
  app4
Function is built in image:
  
Function is deployed in namespace:
  default
Routes:
  http://app4.default.svc.cluster.local
Subscriptions (Source, Type, Broker):
   com.example my-broker

Should we enhance this a bit, since we now are able to create subscriptions (aka Triggers)?

Yes, I believe that we will need to steadily add to func describe as more features are added to the areas it reports.
