- Restored the functionality of specifying basic-auth parameters in a remote's URL.

NOTE: it's much better to specify username/pwd explcitly on the Remote, rather
than relying on embedding them in the URL. This fix will probably be deprecated in
the future.

- Fixes a regression in support for syncing from mirrorlists.

[9312](https://pulp.plan.io/issues/9312)
