* manageiq_alert_profiles: improve handling param requirements
Basically two changes:
* `name` is already required when state is either present or absent, and there are no other states, so making it fully required and removing the conditional
* `alerts` is documented as required when state=present, this has been verified in the code, so added that parameter to the existing `required_if` spec.
* add changelog frag
