Jonathan Rosser cbbd0dee61 Reduce number of processes on small systems
Even the most modest 4C/8T system would run with the maximum 16 processes
due to the calculation being VCPU*2.

This patch makes it clearer that glance_api_threads is the number of
physical CPU, and halves glance_wsgi_processes to physical CPU*2 for
a hyperthreaded CPU.
