Support Knative services

[IGassmann]

It would be nice for k9s to support Knative services (a.k.a. kservice or ksvc).

[cmoulliard]

I fully agree as currently this is really a pain to consult knative services as k9s cannot find them

Example:

[snowdrop@h01-121 ~]$ kc get services.serving.knative.dev -n tap-demo
