Task: rename column master_alias in table _vt.reparent_journal

[deepthi]

Rename master_alias -> primary_alias

This has to be done in 2 phases for +/- 1 version compatibility.

• in v13: add an alter statement that renames primary_alias to master_alias. This will take effect if someone tries to downgrade from v14 to v13. reparent_journal: add backwards compatible alter statement #9439
• in v14: add an alter statement that renames master_alias to primary_alias. This will take effect during the upgrade from v13 to v14. rename master_alias to primary_alias in reparent_journal table #10098
