    hydra: bayfront: Make some NGinx configuration tweaks.
    
    I'm hoping these might help with the "server is somewhat slow"
    messages from guix substitute.
    
    The reuseport option affects all servers, and might help with latency
    and throughput by having connections distributed directly to worker
    processes.
    
    I think epoll might be being used by default, but specify it
    explicitly anyway.
    
    The access log is quite big, so gzip it to decrease disk I/O.
    
    Also increase the number of worker processes.
    
    * hydra/bayfront.scm (%bordeaux.guix.gnu.org-nginx-servers): Use
    reuseport when listening and gzip the access log.
    <services>: Specify use epoll; and increase worker_processes in the
    NGinx global directives.
