Variable FILESYSTEMID picking multiple EFS File System ID

[Alan111S]

Given ... An AWS account containing multiple CPD systems, each in their own VPC, each with an EFS file system in a particular region
When ... running Terraform apply
Expected ... Code in delete-efs.sh and ocp-install.tf for FILESYSTEMID which is used to determine the EFS File System Id is supposed to return only one value.
Actual ... This code in delete-efs.sh and ocp-install.tf for FILESYSTEMID=aws efs describe-file-systems --query 'FileSystems[*].FileSystemId' --output text returns multiple File System IDs when there is more than one EFS file system in the AWS account in a particular region

[Alan111S]

If CLUSTERID environment variable is set, this code will pick the correct id:-
aws efs describe-file-systems --query FileSystems[?Name==\'$CLUSTERID-efs\'].FileSystemId --output text

The code for the FILESYSTEM_ID in create-efs.sh is working ok by the way. It's only delete-efs.sh and ocp-install.tf that have an issue
