Implement !AutoApplyOrder endpoint

[JAAulde]

Sectigo, who bought Comodo, told us that we should start using the !AutoApplyOrder end point in place of the !AutoApplySSL endpoint.

Info on the !AutoApplyOrder endpoint can be found at https://sectigo.com/partner/pci/resources/Sectigo-AutoApplyOrder-v2.2.1.pdf .

Interestingly, it appears to be 100% backwards compatible to the !AutoApplySSL endpoint. Said by the linked doc:

AutoApplyOrder is fully backward-compatible with AutoApplySSL, accepting all the same parameters and able to request all the same certificates.
Changing to AutoApplyOrder is a simple case of changing the API endpoint URL – all the parameters, values and authentication remain the same, and you’ll now have
the ability to request a range of new Sectigo products with simple, minor changes to the API call.

Maybe it doesn't even matter...I'm not sure. As long as they keep !AutoApplySSL in place I guess it's all good (unless a need arises to do something that !AutoApplySSL can't do).

Do you have any thoughts?
