Description (from ent PR):
This PR fixes the regression with SSCT.
The issue is that the SSCT Generation counter was not being loaded from storage, so when it was written to storage during DR promotion it would always be 1. The fix is to load the value from storage during DR promotion. DRs never use the generation counter, but on DR clusters the value in memory will always be 1 less than the value in storage. However, the moment the DR gets updated to a primary, the value from storage will be incremented and written back.
Will open the OSS port after this PR is approved, with a changelog in OSS.
The PR will need to be backported to 1.10.
