Adding simple, scalar parameters for authorize/revoke operations that mimic the legacy CLI.
Merge remote-tracking branch 'origin/develop' into ec2-add-port
Adding an additional event that gets fired when all of the options for an operation have been parsed.  Added handler for this event that provides an error message to user if they mix the --ip-permissions option with any of the scalar options.  Also added a doc event handler to tell the user to use --ip-permissions if they want to specify multiple rules in one command.
