p2p proxy doesn't work with registryfs v2

### What happened in your environment?

Hey, we tried to upgrade our overlaybd installation from 0.6.17 to 1.0.13 and found out p2p proxy doesn't work with registryfs v2. The new http client in registryfs v2 is not able to parse the local p2p endpoint correctly. See the following logs:

```
There are two errors in the above log.
1. The url host is parsed incorrectly: `23:29:32.182682|DEBUG|th=00007E28A80866C0|message.cpp:312|reset:requst reset [u.host()=**redacted**.blob.core.windows.net][enable_proxy=0]`
2. For some reason, the request to the azure storage account also failed (got 400 code).
