Sylvain Bauza c102600d59 Add reserved_host_cpus option
When discussing for the blueprint placement-claims we had a consensus on
using reserved values for helping operators to provide overhead limits
for all the instances.

Since we only had 2 opts for RAM and disk, we missed a possible CPU one.
This patch is adding that one.

features:
- A new configuration option ``reserved_host_cpus`` has been added for
compute services. It helps operators to provide how many physical CPUs they
would like to reserve for the hypervisor separately from what the instances
use.
