Fixes#480

- Add --type flag to filter source list based on source type
- Add unit tests
- Add e2e tests

* Update group for ApiServerSource in tests
* Add kn duck source type for holding common eventing source fileds
- Common infromation from sources are extracted into a struct
for source list command output

and doesn't know the details about extracting this info from multiple
types of sources received
- Group and Version for list is set to empty string and Kind to 'List',
if printed a source list with multiple types of sources in machine readable
format
- Group, Version and Kind for list are kept intact if printed a source list
with same type of source objects in machine readable format
* Update go.sum
* Add WithType builder for listing source
- Separate the flags definition
- WithType builder can be re-used to filter the source types
- Add unit tests
