[Filebeat] AWS CloudWatch Input add multiline support

[gomclifton]

Mirroring request for S3 multiline input, #23350

Describe the enhancement:
At the moment Filebeat AWS CloudWatch Input doesn't offer multiline support

Describe a specific use case for the enhancement or feature:
In AWS Cloudwatch streaming to SQS there might are occasions for log files that hold multiline log lines like for instance AWS Hadoop or other Java products.

We currently have AWS SQS logs in Cloudwatch that need multiline processing in order to get into ELK pipeline.

Is there any workaround at least for this? I tried using logstash multiline codec but it refuses to work when filebeat is the input.
So, no multiline in filebeat input, no multiline in logstash. I'm not sure how to workaround this one
