Provide a basic search engine for builds
Summary:
This supports a few basic use cases that aren't served by the buildable search engine:
- I'm trying to discover when the last time that this particular build plan failed was.
- I want to know if any builds have deadlocked.
- At a glance, I'm more interested in what build plans are running, not which buildables are being built. This is more often than not the case.
