Module to ship AWS Cloudwatch logs to AWS Elasticsearch. This assumes that your AWS Elasticsearch is running inside a VPC and your Lambda will be deployed inside that VPC. The needed IAM rights + securitygroups and rules are created. To make this work, you need to choose a subnet that has access to the AWS elasticsearch service.

• [elasticsearch_sg_id]: String(required): Security group ID of the AWS elasticsearch service.
• [elasticsearch_dns]: String(required): Elasticsearch DNS hostname
• [environment]: String(required): the name of the environment these subnets belong to (prod,stag,dev)
• [subnet_ids]: List(required): Subnet IDs you want to deploy the lambda in
• [log_group_name]: String(required): Cloudwatch logs loggroup name to use
• [aws_account_id]: String(optional): Your AWS account ID. Default to your current AWS account
• [aws_region]: String(optional): AWS region where you have your AWS cloudwtach loggroup deployed in. Defaults to your current region
• [retention_in_days]: Int(optional): How many days the lambda logs are kept. Defaults to 30 days
