cleanup printers some more
This cleans up some more dead printer flags and unnecessary arguments for various methods. We're getting closer. Still need to clean up some ugly around `PrintSuccess` and then its time to start trimming layers.

kubectl config get-contexts: sort output
This sorts the output of kubectl config get-contexts because the ordering is otherwise non-stable and makes it harder to find the context you're looking for when you have more than a few.
```release-note
The output of kubectl config get-contexts is now sorted alphabetically by the context name.

Correct case for starting character of option string
**What this PR does / why we need it**:
Kubectl-conventions.md states:
"Flag descriptions should start with an uppercase letter and not have a period at the end of a sentence"
There are numerous cases where this is violated in `kubectl/cmd`. This PR is the result of an audit of all source files under `kublet/cmd` and corrects the case of the initial Flag description character.

to format output for a resource. This functionality is guarded by a boolean
flag 'use-openapi-print-columns'.

returns nil for both printer and err removing any potential panics that
may arise throughout kubectl commands.
