Add environment variables to the influx --help command

[russorat]

in the 1.x world, the --help command would show the environment variables that could be set as well so that the command could be shorter. I know about INFLUX_TOKEN but are there others for the ORG or BUCKET as well?

It would be helpful to have them here:
