Review Comment:
We should check the `InstancePartitionsType` of the entry to decide how to
assign the segment. The current logic is for `CONSUMING` type only, and we
should add one for `COMPLETED` type, which should be similar to
`OfflineSegmentAssignment.assignSegment()`

Review Comment:
We should use `COMPLETED` type only if the `COMPLETED` instance partitions
exists or the tag override is configured. If segment relocation is not
configured, we should follow the same assignment as the `CONSUMING` segments.
Let's keep the comments for the upsert case. For upsert segments, we should
always use the `CONSUMING` type.

Review Comment:
Move this implementation to the `BaseTableDataManager`. It is common for
both offline and realtime table
