support retention for cloudwatch_logs output

[markuman]

Is your feature request related to a problem? Please describe.
Without retention, logs are kept forever in aws cloudwatch logs.

Describe the solution you'd like
While auto_create_group On is supported, set a retention as an addition option should also be supported.

See: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/logs.html#CloudWatchLogs.Client.put_retention_policy
