zuul-launcher to zuul-executor.

Zuul has a modular architecture for executing jobs. Currently, the
only supported module interfaces with Gearman_. This design allows
any system to run jobs for Zuul simply by interfacing with a Gearman
server. The recommended way of integrating a new job-runner with Zuul
is via this method.
If Gearman is unsuitable, Zuul may be extended with a new launcher
If Gearman is unsuitable, Zuul may be extended with a new executor
module. Zuul makes very few assumptions about the interface to a
launcher -- if it can trigger jobs, cancel them, and receive success
executor -- if it can trigger jobs, cancel them, and receive success
or failure reports, it should be able to be used with Zuul. Patches
to this effect are welcome.
