Connection to Harbor and download failed , when Harbor reached maximum number of open active connections.

Bug report:

Connection to Harbor and download failed , when Harbor reached maximum number of open active connections.

Expected behavior:

When Harbor or registry reached maximum number of open connections, new request should wait until open requests closed.
But, we saw when Harbor reached threshold open connections, some of new requests failed with 401 error.

ERROR

FATAL: Unable to handle oras://harbor-registry-url.com uri: failed to get checksum for oras://harbor-registry-url.com: while resolving reference: pulling from host harbor-registry-url.com failed with status code [manifests stable]: 401 Unauthorized

Environment:

• Dragonfly version: 2.09
• OS: Linux (SLES15)

@gnr1227 Upgrade dragonfly the version, or harbor limits the number of connection and gc idle connections.
