Push the calculation of target counts into the SQL query, rather than loading
all of the targets and then counting them. This provides a dramatic (>100x)
speedup in loading of the manage packs page when large numbers of hosts are
present.
Closes#1426
Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
