Fixes #29413 - Add fuzzy subcommand matching

[ofedoren]

Adds fuzzy (prefix) subcommand matching as in https://github.com/tstrachota/hammer-cli-experimental.

Allows to use 'reduced' hammer commands, for example:

• hammer org l instead of hammer organization list
• hammer ro s --id 1 instead of hammer role show --id 1
• hammer li l instead of hammer lifecycle-environment list

If there is anthoer subcommand that starts with the same prefix, the help error is shown, e.g.:

> hammer host i
Error: Found more than one command.

Did you mean one of these?
	index
	info

Also adds possibility to use aliases for commands, for example:

• hammer host show --id 1 instead of hammer host info --id 1
• hammer host index instead of hammer host list

PR that adds aliases for info/list/delete commands: theforeman/hammer-cli-foreman#512

@ares, you might want to take a look at this :)

Woot, I won't be able to properly review anytime soon, but quick read seems ok

@ofedoren , I've tested it and it's working great,
can you add some documentation on how to use it in a new command?

@shiramax, done: https://github.com/theforeman/hammer-cli/blob/aa8a2d753bbeb45a3745ae7e2c3a872139b48b74/doc/creating_commands.md#aliasing-subcommands :)
