Update internal unconditional rollover calls to use lazy rollover

[dakrone]

Description

Currently we have some of our IndexTemplateRegistry subclasses that invoke unconditional rollovers after templates have been upgraded. One thing that would be good to do is to make use of the recently merged lazy rollover flag for these calls.

We can look at uses of the applyRolloverAfterTemplateV2Upgrade() flag to see where these are used.
