[Backport 4.2.x] WMS GetMap HEAD request error response - check response status defined (geonetwork#8076)

* WMS GetMap HEAD request error response - check response status defined

Follow up of geonetwork#7000

* WMS GetMap HEAD request error response - Don't use CORS interceptor.

If the map service doesn't support HEAD (or CORS for HEAD requests), all other requests to the server go through the http proxy, even if the server supports CORS for these requests

* Proxy / Make distinction between methods. (#101)

Some servers provides CORS header for some method eg. GET and not for other eg. HEAD.
In such case, if a failure occurs on a HEAD request, then the proxy is activated for that domain but is not needed for GET request. If user is anonymous, then proxy forbid access to the domain (if the domain is not in the link analysis table with default configuration) and simple action like `GetCapabilities` will fail.

Add the method to the domain as key to know if the proxy has to be used or not.

Can be tested with https://haleconnect.com/ows/services/org.789.b36c0053-db6b-4fe7-9402-4e5d8ac35e06_wms
