r/aws_elasticache_replication_group: Remove auth_token_update_strategy default

[jar-b]

Description

The auth_token_update_strategy argument was added in #34460 with a default value of ROTATE to retain backward compatibility with previous provider versions where this was hardcoded into update operations. In v6.0.0, the default value should be removed and this argument should be required when auth_token is set to ensure practitioners are aware of the rotation strategy being used when credentials are added or modified. This will be a breaking change.

Can confirm. It broke out deployment pipeline:

Error: changing auth_token for ElastiCache Replication Group (<rep-group-name>): InvalidParameterCombination: Auth tokens can't be enabled with a user group already associated. Pass RemoveUserGroups to proceed.

Hey @CbaSage - this regression should have been fixed with #34600, released in v5.28.0 last night.

This issue is focused on future breaking changes for the next major release (v6.0.0). For the v5.X series, the default value will remain to keep backwards compatibility. This comment contains a more detailed explanation for this, if interested.

hi @jar-b ,
This issue is still not fixed. When i am trying to import aws_elasticache_replication_group, it automatically adds auth_token_strategy in terraform plan . I had t use lifecycle policies to ignore the change. Can we relook at this once
