feat: reverse api <-> route alias

[MichaelGoberling]

Make aio runtime api the main command for managing Openwhisk API routes so it shows up in the aio runtime / rt help text, just like the wsk cli.

Notes

• The Runtime plugin will still support using aio runtime route just as before
• We may want to change this back to once the RT documentation is changed to reference the aio cli.
