Release Note

feat(ci): local installation procedure

wdyt about the make install- to create the namespace when the one set in the variable is not already created ? As this from a developer perspective, it seems there is no harm to have this shortcut and it saves a few keystrokes.

I had thought about it. However I think it is better in order to educate the developer and to make him aware that the default ns is "camel-k" where there is a global operator installed.
