Make EAP fee description check more flexible

Currently we determine fee type from the fee extension description by checking if the format string of the FeeType contains the description we received. The formatting string for EAP is "Early Access Period, fee expires: %s", so the fee description generated by a domain check command, like "Early Access Period, fee expires: 2022-03-01T00:00:00.000Z", is not recognized as EAP.

This CL adds the ability to add arbitrary extra description strings to the FeeType for a description to match against. It also changes the match to "the given description contains any of the strings from the list of format string plus extra description strings".

For EAP, we added an extra description string "Early Access Period", so any fee description that contains "Early Access Period" will be matched to EAP FeeType, including the specific description (that contains the expiry time) that we send in a domain check.

Also improved error message on multiple fee type matching.
