[PLAT-14008] Avoid rolling YBA managed n2n certificates when not need…

…ed (e.g. during Gflag Upgrades)

Summary:
Removed certificates rolling for the case of gflags upgrade.
Now certificates are rolled/generated only for these actions:
1) Configure everything (this happens at the start of universe creation)
2) Software upgrade (because there was inconsistency between certs location for old releases)
3) Tls toggle
4) Rotate certs

Test Plan:
Create universe with tls enabled - verify everything is ok
Add nodes to universe - verify certs are present
