Knative Client release v0.18.0

Release 0.18.0 of the Knative client kn comes with some bug fixes plus some additional support for Knative eventing features

Meta

The compile dependencies have been updated to Knative Serving 0.18.0 and Knative Eventing 0.18.0.

Eventing support

The kn channel support has been extended by a kn channel list-types which shows you all the channel types that are available in the cluster.
This information can be used to select the type when creating a channel with kn channel create.

Subscriptions which connect a sink with a channel can now be fully managed with kn subscription commands.

Aliases

For a better user experience we added some aliases for commonly used commands:

command	alias
service	ksvc
service	services
revision	revisions
route	routes
source	sources
broker	brokers
trigger	triggers
channel	channels
subscription	subscriptions
subscription	sub
plugin	plugins
list	ls

Other

Some other minor features has been added:

• You can use now --annotation-service and --annotation-revision to select the part of Knative service where you want to put an annotation on. With --annotation you add an annotation to both parts, the Knative service's annotation and to the annotation of the Pod template used to create revisions.
• A new option --scale-init allows to specify the initial number of pods that should be created when a Knative service is created. By default this number is one, but you can set it to 0 if you don't want to create a pod during service creation.

You can find the full list of changes in the CHANGELOG.
