Allow long daemon log messages to be expanded

Summary:
Ref T3557. We summarize long messages, but don't let you see the entire message. This is occasionally inconvenient, and I'm planning to add more prefix junk to some messages for T2569.

Provide a link you can click to see the full message.

This isn't javascripted because a ton of these can make the page ridiculously enormous and it seems unlikely you'd care much about all of them.

Use PhutilProxyException to disambiguate repository pull errors

Summary: Ref T2569. When repository pulls fail, they don't necessarily list identifying information about which repository failed. Use a proxy exception to list that information.

Surface task queue temporary failure rate in Daemon console

Summary: Fixes T3557. One thing which made T3557 kind of a mess was the lack of information about progress through temporary failures. Add a column which records a task's last failure time, and surface it in the console.
