[BACKPORT 2.20.0] [PLAT-11526] Add HA disable cert validation runtime…

… conf

Summary:
This runtime conf is respected by the code but not settable via the UI. Adding this entry
to GlobalConfKeys should allow this to happen.

Test Plan:
(Tested on master)

Brought up YBA1 and YBA2 with yba-installer, setup HA with no trust store. Created a univ on YBA1. Verified primary YBA1 was unable to send backups to standby.
Set the config "yb.ha.ws.ssl.loose.acceptAnyCertificate" on YBA1 and restarted it (the change listener did not pick up this change and notify existing ws clients)
Verified that HA started to work correctly with YBA2 receiving backups
Promoted YBA2 and verified universe could be seen here and that YBA1 was demoted succesfully.
