    New python lib with only the executor driver.
    
    This patch produces a new python egg, mesos.executor, which contains only the
    code needed to create a MesosExecutorDriver.  By doing so, the linker can remove
    unused code in libmesos_no_3rdparty.a, and therefor not include any external
    dependencies in the resulting _mesos.so.

> Currently, when running tasks in docker containers, if the executor uses the mesos.native python library, the execution environment inside the container (OS, native libs, etc) must match the execution environment outside the container fairly closely in order to load the mesos.so library.
> The solution here can be to introduce a much lighter weight python egg, mesos.executor, which only includes code (and dependencies) needed to create and run an MesosExecutorDriver.  Executors can then use this native library instead of mesos.native.
