Context sensitive Bash completion

[rhuss]

Feature request

kn completion is currently based on the auto generation of the bash/zsh completion code by cobra. It lacks the the possibility to complete on context sensitive information likes service or revision names, something that e.g. kubectl allows.

We should extend the completion code to allow completion on those resources. The way how kubectl does it could be taken as an inspiration.

UI Example

kn service describe my<TAB>

would complete to "myservice" if there would be a Knative service installed that is called "myservice".

Here are the smaller issues tracked by this issue:

• Add completion on option to the Bash completion code #1374
• Added autocompletion for service name #1547
• Added autocompletion for broker #1559
• Added completion for revision resource #1560
• Added completion for route name #1561
• Added completion for domain command #1562

Let's add #1374 first and then continue with this story.

@rhuss @dsimansk should we reopen this as only one resource has been addressed?

[rhuss]

Good point, let's keep this issue for tracking the overall story.

Sorry about the mess from too many PRs. I think we can reopen the issue and I can create subtasks for the remaining resources so this doesn't get closed before completion
