Steve Domino 6d2f1d2fa7 Ability to hide commands from usage/help text
Added the ability to have hidden commands that cobra will still run as intended, however they won't show up in any usage/help text

adding internal field to command

private is a better name

hiding private commands in default help/usage

opting for 'hidden' over 'private'

updating all 'help command' checks to exclude hidden commands

updating how commands are displayed in usage/help text by updating/adding some methods. added tests for hidden/deprecated commands

making command hidden when testing hidden command execution

test now leverage the included suite and are much less custom. also removed deprecation tests, once I discovered them in cobra_test.go

updating hidden command test to be more reliable

removing unnecessary () when checking len(c.Deprecated)

updating command comments to be godoc friendly
