Add commonly mistaken aliases

[brooksmtownsend]

• chore(ctl): add alias for key/keys link/links
• chore(ctl): support --domain alias

Feature or Problem

This PR adds a couple simple aliases where users may forget to make the subcommand a plural subcommand or where existing muscle memory may kick in (e.g. going back and forth between the NATS CLI with --domain and wash with `--js-domain)
