Proposed changes

Users may change a colocate table's replica allocation. So may be different with the group schema's replica allocation.

When relocating colocate tables, it should use group schema's replica allocation.

Further comments

If this is a relatively large or complex change, kick off the discussion at dev@doris.apache.org by explaining why you chose the solution you did and what alternatives you considered, etc...
