Elasticache Replication Group allows replication_group_id to be longer than aws will accept

[devinsba]

replication_group_id is limited to 20 characters by the provider but the AWS API only allows 16. These should really match to save users some frustration.

* aws_elasticache_replication_group.bar: Error creating Elasticache Replication Group: InvalidParameterValue: Replication group id should be no more than 16 characters.
    status code: 400, request id:

Hi @devinsba

Apologies for the confusion here - this is very odd! The AWS documentation says the following:

--replication-group-id (string)

The replication group identifier. This parameter is stored as a lowercase string.
Constraints:
A name must contain from *1 to 20* alphanumeric characters or hyphens.
The first character must be a letter.
A name cannot end with a hyphen or contain two consecutive hyphens.

This documentation was what the resource was based on - i can update this now
