feat: setup explorer on argus

[jakeyheath]

Summary

This is a demo PR of what the workflow and new configuration for the argus platform would look like. All new infra configuration is in the .infra folder and split by environment (very similar to how .happy looks). However, instead of a terraform files, there are YAML configuration files. These files look more like native kubernetes setting and load a Helm chart.

Details

• .infra/common.yaml - Configuration for all environments. Think of this as your base set of common configuration.
• .infra/rdev/values.yaml - Configuration overridees for the rdev environment. These settings can add or overwrite the configurations set in .infra/common.yaml.

References

• The helm chart source is here.

Notes

• There is an open bug in tiledb that isn't allowing us to use the pod's EKS IAM role. For now, we have manually made an AWS user and associated it with the policy and stored the credentials in the K8S secrets.

• only rebuild if the source changes
• don't build and push on the main branch (the container image should already be built by the time it merges to main)

Utilizes our ECR pull through cache so we don't accidentally hit dockerhub rate limit issus. Also allows us to do security scanning and other security monitoring on the images we pull.
