Milo: Increase test coverage for appengine/buildbot

Adds new tests and slight refactoring including:
* Move most of the html test data out of the buildbot module into the frontend module.  Because that code is only executed by the frontend test code, it makes more sense to put it there.  The intention is to do the same with the other modules.
* Because of the above, make the build implementation public.
* Add new test cases and test files.

This yields 81.1% test coverage for the buildbot module.

luci-go: LUCI services and tools in Go

GoDoc Build Status Coverage Status

Installing

go get -u github.com/luci/luci-go/client/cmd/...
go get -u github.com/luci/luci-go/server/cmd/...

Code layout

  • /appengine/... contains AppEngine server code. It imports packages from /common/... and /server/....
  • /client/... contains all client code.
  • /common/... contains code and structures shared between all of /appengine/..., /client/... and /server/...; for example, the structures used by the server APIs. These are inherently APIs.
  • /deploytool/... contains the LUCI cloud services deployment tool.
  • /logdog/... contains LogDog client and server code, as well as APIs, protobufs, and support libraries.
  • /server/... contains standalone server code. Its packages are reusable by /appengine/....
  • /tools/... contains support tools used by other LUCI components.

Versioning

  • Branch go1 contains the stable code.
  • Branch master constains the latest code.
