Drop support for minishift?

[tadayosi]

Today I tried minishift but it no longer woks for me (got the following error). Is there anyone who can/does still use minishift with Camel K? Otherwise it's good time to drop documentation and installation method (script) for minishift.

Yeah, I agree. I think we should drop support and remove all the docs related. I've tried many times in the recent past and never succeeded.

[davsclaus]

Yes drop it

Relates to #1550. CI still relies on it, so it's surprising it doesn't work. We keep it as it's the only workflow that covers RBAC. However, any references from the documentation should be removed.

@astefanutti If I'm not mistaken, CI just uses an old version of oc and relies on oc cluster up, not minishift. Here I'm just talking about minishift. I think it's ok to keep OpenShift 3 support.

@tadayosi ah right, I inferred OpenShift 3 🙃. Sounds good.
