Deploy kobectl as kubectl plugin

[acharal]

Nowadays, kubectl allows for plugins. Kobectl can also be deployed as such.

Since kobectl wraps (as opposed to extending) kubectl, I think it would be either unnecessarily verbose or confusing. If we add a "kobe" subcommand and then the current kobectl syntax follows, it would be unnecessarily verbose. If we adds command to the side of the kubectl ones it would imply that kubectl commands and kobectl commands are to be mixed to perform KOBE-related tasks; which can have unintended effects and invalidates the assumption that the user has not interacted with the cluster in any other way except through kobectl. I am not sure we are actually relying on this assumption as things stand, but I think it is a useful assumption.
