[BREAKING] Automated testing

[RothAndrew]

BLUF

• Add new example called complete that is capable of running in either "insecure mode" or "secure mode" by switching which tfvars overlay is used. Insecure mode is ready as part of this PR, secure mode will come next
• Make the documentation for deploying an example way easier by leveraging make, docker, and terratest
• Add an automated test that tests the complete example in insecure mode

Next Steps after this PR merges

NOTE: None of this is being done as part of this PR. This PR creates an entirely new example folder called complete

1. Delete the complete-managed-nodegroup example
2. Add secure mode to the complete example
3. Add an automated test for secure mode
4. Delete the complete-self-managed-nodegroup example

BREAKING CHANGES WERE MADE TO THE BASTION MODULE

Changes were needed in order to add uniqueness to resource names which is important when offering the ability to do automated testing.

• [Breaking] Change variable name from optional (with default value of "") to required
• [Breaking] Rename variable access_log_bucket_name to access_log_bucket_name_prefix
• [Breaking] Rename variable bucket_name to session_log_bucket_name_prefix
• [Non-Breaking] Update the count field on several resources to account for variability in resource names (the way it is in main does not allow for any variability, it threw error The "count" value depends on resource attributes that cannot be determined until apply, so Terraform cannot predict how many instances will be created.)

BREAKING CHANGES WERE MADE TO THE S3-IRSA MODULE

Changes were needed in order to add uniqueness to resource names which is important when offering the ability to do automated testing.

• [Breaking] Remove variables bucket_prefix and cluster_name and replace them with variable name_prefix
