Remove EKS cloudwatch group creation

General MR

Summary

The EKS pipeline creates a cloudwatch group for EKS control plane cluster logs. This sometimes leads to issues. If the log group doesn't cleanup the next pipeline will attempt to create the log group with the same name for the same git commit. This fails because the log group already exists. This MR contains the following changes:

• Disabled cloudwatch log group creation using the EKS module inputs.
• Bump cluster version in env specific folders to 1.27 for EKS version
• Ran terraform format to format the .tf files

Relevant logs/screenshots
