feat: add kubectl auto-completion

[v1k0d3n]

one nice (and extremely simple) change that we can make is to have kubectlauto-completion.

this can be done with a simple ansible lineinfile EOF in ~/.bashrc.

source <(kubectl completion bash)

i can get back to this later, but if someone in the community wants to add to the playbooks...that's fine also. i just wanted to create the feature request before i forget it (as i'm working on something else).

some additional details if someone wants to get fancy: kubectl auto-completion
