[I] Expose transporter details per protocol [maven-resolver]

["kwin (via GitHub)" <gi...@apache.org>]

kwin opened a new issue, #1770:
URL: https://github.com/apache/maven-resolver/issues/1770

   ### New feature, improvement proposal
   
   Currently it is impossible to tell in advance which transporter implementation is used for which kind of (remote) repository resolver/upload request. In order to ease debugging, this should be exposed via API (without the need for having a concrete RemoteRepository).

   Problem right now is that `TransporterFactory.newInstance` always takes a `RemoteRepository` to check if it should be used. It fails with an exception if it doesn't support the given repository url. Probably this should be refactored so that a more targeted lookup can be performed (also in https://github.com/apache/maven-resolver/blob/ec52693dc400578dd03f731c88c58807cca6a148/maven-resolver-impl/src/main/java/org/eclipse/aether/internal/impl/DefaultTransporterProvider.java#L104).
   
   Maybe adding another method `boolean canHandle(String protocol)` (by default always returning true) to `TransporterFactory` in combination with something like `String getDescription()` (returning some explanation on which library is used etc). would be reasonable.
