Add ubuntu test, terraform and validation files (#364)

*Issue description:* Existing testing framework did not have ubuntu test
for java

*Description of changes:* Added java ec2 ubuntu test along with
terraform files and validation files

Test link:
https://github.com/Jeel-mehta/aws-application-signals-test-framework/actions/runs/13001021774

*Rollback procedure:*

<Can we safely revert this commit if needed? If not, detail what must be
done to safely revert and why it is needed.>

*Ensure you've run the following tests on your changes and include the
link below:*

To do so, create a `test.yml` file with `name: Test` and workflow
description to test your changes, then remove the file for your PR. Link
your test run in your PR description. This process is a short term
solution while we work on creating a staging environment for testing.

NOTE: TESTS RUNNING ON A SINGLE EKS CLUSTER CANNOT BE RUN IN PARALLEL.
See the
[needs](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#jobsjob_idneeds)
keyword to run tests in succession.
- Run Java EKS on `e2e-playground` in us-east-1 and eu-central-2
- Run Python EKS on `e2e-playground` in us-east-1 and eu-central-2
- Run metric limiter on EKS cluster `e2e-playground` in us-east-1 and
eu-central-2
- Run EC2 tests in all regions
- Run K8s on a separate K8s cluster (check IAD test account for master
node endpoints; these will change as we create and destroy clusters for
OS patching)
