Updated Hooks to fix failure during master failover.

The ExecutorInfo is immutable, and so the environment decoration is deferred
until containerizer launch. The new slaveExecutorHook simply notifies the hook
module of a new executor being launched. The environment decorator hook for
containerizer launch update it's environment variables as gathered from the hook
modules.
