-=== Add global retention in data stream lifecycle
-Data stream lifecycle now supports configuring retention on a cluster level, namely global retention. Global retention 
-allows us to configure two different retentions:
-
-- `default_retention` is applied to all data streams managed by the data stream lifecycle that do not have retention
-defined on the data stream level.
-- `max_retention` is applied to all data streams managed by the data stream lifecycle and it allows any data stream 
-data to be deleted after the `max_retention` has passed.
-
-Furthermore, we introduce the term `effective_retention` which is the retention applied at a certain moment to a data
-stream considering all the available retention configurations.
