This supports the simple remote option eg. ‘instances add –remote “qa”` It will establish a connection to the pre-configured appliance named “qa” The calling command can populate @appliances and/or @appliance_name Otherwise, the current active appliance is used… This returns a new instance of Morpheus::APIClient (and sets @access_token, and @appliance) Your command should be ready to make api requests after this.
