      Description

      Currently the balancer runs on all blockpools. Allow an admin to run the balancer on a set of blockpools. This will enable the balancer to skip blockpools that should not be balanced. For example, a tmp blockpool that has a large amount of churn.

      An example of the command line interface would be an additional flag that specifies the blockpools by id:

      -blockpools BP-6299761-10.55.116.188-1415904647555,BP-47348528-10.51.120.139-1415904199257
