Rename transport actions

Currently, the suite still defines transport action IDs like cluster:admin/searchguard/config/update.

We need to find a migration path for Eliatra Suite transport action IDs.

Mapping for action names

Legacy	New
cluster:admin:searchguard:...	cluster:admin:eliatrasuite:securityplus:...
cluster:admin:searchguard:signals:...	cluster:admin:eliatrasuite:alertingplus:...
(anything independent of security and alerting)	cluster:admin:eliatrasuite:...
