Support renewal of certificates for API Management custom domain endpoint through ./well-known
This applies to API Management instances with custom domain configured:
We would like to use automatic renewal of the SSL certificate for the endpoint, but there currently is no acceptable method to support the proof of ownership required the certificate renewal provider of Azure: GoDaddy.
Domain verification through DNS TXT record is not possible as it needs to be on root level of azure-api.net (which is owned by Microsoft and not the customer)
HTML web page method is not possible as not possible to publish a page to .well-known/pki-validation/godaddy.html on the API Management endpoint.
Email verification is a poor method for larger enterprise as the administrator@, hostmaster@, admin@, postmaster@ and webmaster@ may not be monitored.
As a solution, API Management should allow administrators to publish required web-pages under the .well-known/ path.
