Cache invals with redis and postgres should fallback on the pubsub class

Since NXP-23055 (https://github.com/nuxeo/nuxeo/commit/c08bfd67d08693e27cb6503839d1eff0f21d3f2c#diff-ed13ab81e9b2d0e814334cec41bdc893) the RedisClusterInvalidator has been removed.

NXP-23996 has cleaned the configuration templates to not use that class anymore: https://github.com/nuxeo/nuxeo/commit/c02aea3d2d1792a353b59c4c29cc05b04fde779d.

But unfortunately this has not been backported to 9.10, therefore anyone using Postgres,mysql or oracle and who in the past has used that setting repository.clustering.invalidation=redis will have a NoClassFoundException for the class RedisClusterInvalidator on startup.

When repository.clustering.invalidation=redis setting is used it should fallback to use the VCSPubSubInvalidator as done that under the hood use Redis
