Don't automagically add "[OPTIONS]" to usage

This removes the logic to automatically
add [OPTIONS] to the usage output.

The current logic was broken if a command
only has deprecated or hidden flags, and
in many cases put the [OPTIONS] in the
wrong location.

Requiring the usage string to be set
manually gives more predictable results,
and shouldn't require much to maintain.
