### What problem does this PR solve?
Exposes cloud balance related metrics to show whether the compute group is
performing balance scheduling. When `*_balance_num` metrics are all 0, the
current compute group is considered to be in a balanced state.
Note: These metrics are valid only when requesting the fe master (balance
scheduling is performed on the fe master)
