Description

Is your feature request related to a problem?

When we sync table data using multi ticdc node ,we may encounter load not balance problems.And ticdc not support dynamic balance region between different ticdc nodes.

Describe the feature you'd like

We can support manually balance the specific region to the low load ticdc first,example:

cdc ctl hot region {node-A} ### top 10
cdc ctl balance region {region-id} {node-A} {node-B}

In this way, we can have a solution to solve this problem and dispel doubts for our users.
