    tcwg-base/tcwg-llvmbot: Add a script to generate Docker core assignments...
    
    ...in a declarative manner.
    
    I want to add more libcxx containers and I am sick of manually working
    out the --cpuset-cpus= numbers each time. So get_cores.py will do this
    for us now.
    
    It works by us setting the number of cores we want for each container,
    on each machine, in the script. Then the script converts that
    into actual core numbers, and validates that the layout can work.
    
    Then prints either the "--cpuset-cpu=X-(X+N)" we should use,
    or "" if the container has no specific allocations. start.sh will
    then use that value in the docker run command.
    
    This get_cores.py can be run locally just by giving it a container
    name, and there is a debug mode --debug so you can see the
    calculated layouts and how many cores are unallocated.
    
    For now we assume no bot will be run in normal and silent on
    the same machine, and that all machines are 160 Jade machines.
