Update Secure Agent's EC2 instance for a better instance - WISCALERTS-2

• Adjusted the instance to be a t2.xlarge since we are going to have more load.
• Increased container memory to 15 GiB.
• Increased EC2 instance's EBS root volume to 40 GB.
• Re-named the profile to indicate the environment it's associated to.
