THREESCALE-8707 Fix apply app

Jira: https://issues.redhat.com/browse/THREESCALE-8707

The source issue was that applications were created populating both user_key and application_id regardless of the product's authentication mode (backend_version attr). When the auth mode is user_key (backend_version attr equals '1'), the application_id was also populated. After user key regeneration, the user_key changed but not the application_id. When the toolbox asked for an application with user_key application_parameter10,3scale returned not found as expected. Then the toolbox asked for an application with application _id application_parameter10 which existed, but since the auth mode is user_key 3scale still returned not found. In the last step, when the toolbox tried to create a new app with application_id application_parameter10, 3scale complained saying it is already used and the command failed. This is because the regenerated application, somehow (internal stuff), still kept application_id as application_parameter10, hence failing the creation step.

The fix consists on populating only required fields. No more.

verification steps

• Create a new application with command "application apply"

3scale --verbose application apply --account=<value> --service=<value> --description=<value> --name=<value> --plan=<value> <remote> application_parameter10

• Retrieve the application attributes. It must return recently created app

3scale --verbose application show <remote> application_parameter10

• Regenerate the User Key through the Admin Portal UI and check the attributes again, so the application user_key has anew value and not application_parameter10 as defined in the first step:

3scale --verbose application show <remote> application_parameter10

The following error should be returned:

{
  "code": "E_3SCALE",
  "message": "Application application_parameter10 does not exist",
  "class": "ThreeScaleToolbox::Error"
}

• try to rerun the command mentioned in the first step, i.e. create a new application with the application_parameter10 user key

3scale --verbose application apply --account=<value> --service=<value> --description=<value> --name=<value> --plan=<value> <remote> application_parameter10

This command should not fail and you should end up having two applicatins with the same name and descriptions, but different user key.
