lfs: handle URLErrors to add additional information Sometimes the blob server is hit first (e.g. on push), and sometimes it's hit last (e.g. pull). Throw in depth first subrepo operations, and things quickly get insane. It wasn't even mentioning LFS, so just saying "connection refused" can be confusing- especially if the blob server is a secondary server and connecting to the repo server works. The exception handler for the transfer handler will print the full path to the blob, but that seems fine given that it might be necessary to debug a second server. (We don't yet support a standalone blob server, so the handler for the Batch API will cover 99.9% of the current problems. But it might as well be handled now while I'm thinking about it.) The function for translating to a message was mostly borrowed from scmutil.catchall().
