redhat_subscription: Add server_prefix and server_port as supported arguments (#2779)

* Add server_prefix and server_port as supported arguments for the redhat_subscription module.

* Adjust the argument sequence in the test case to be consistent with the original code in line 364 in redhat_subscription.py and add the changelog fragment.

* Grammatical changes such as adding full stops and using 'an HTTP' instead of 'a HTTP'.

* Commit the suggested changelog update.
