feat(dms): add new check dms_endpoint_redis_tls_enabled

[danibarranqueroo]

Context

This new check verifies whether AWS Database Migration Service (DMS) endpoints for Redis are configured with TLS (Transport Layer Security). The control fails if TLS is not enabled for the endpoint.

TLS provides end-to-end encryption for data in transit, ensuring secure communication between source and target databases during migration. Enabling TLS helps prevent unauthorized access to sensitive data, mitigating risks such as data breaches and interception.

RDS endpoints have a parameter inside the Redis Settings called SslSecurityProtocol. This allows to enable or disable the connection to a Redis target endpoint using Transport Layer Security (TLS). Valid values include plaintext and ssl-encryption. The default is ssl-encryption. The ssl-encryption option makes an encrypted connection.

Description

Added new check dms_endpoint_redis_tls_enabled with its unit tests.
