shicong 66d98c8d66 Add SetNumInstancesCommand in Nomulus tool to adjust the number of instances
for a given service and version at runtime.

Note that this CL only supports the adjustment for a given service and version. I will add another functionality to let this command be able to detect all non-live versions automatically and apply the adjustment.
