Motivation:
In cases when an application is running in a container or is otherwise
constrained to the number of processors that it is using, the JVM
invocation Runtime#availableProcessors will not return the constrained value but rather the number of processors available to the virtual machine. SOFAJRaft uses this number in sizing various resources.
Additionally, some applications will constrain the number of threads
that they are using independenly of the number of processors available
on the system.
Thus, applications should have a way to globally configure the number of processors.

Result:
Fixes #180
