Support `-u`, `-p` and other shorthand startup params

Problem to Solve

The command to connect to TypeDB Cloud is verbose - even in its canonical form

Current Workaround

./typedb console --cloud=<snip> --username <snip> --password <snip>

Proposed Solution

./typedb console --cloud=<snip> -u <snip> -p <snip>

Additional Information

As an aside, the above command currently prints:

Unknown options: '-u', '<snip>', '-p', '<snip>'

Although it's probably fine to print the password in plaintext given it was supplied by a plaintext command, it feels wrong - and therefore we should probably not do it.
