#444 K8S Migration

[xMHW]

Summary

Migration of taxi backend to sparcs-cluster.
Major changes

• environment variables managed with deployment/base/server/configmap.yaml and sealed-secret.yaml
• deploy to EKS based Sparcs-Cluster
• gitops supported based on argocd, definitions under deployment folder
• domain route rule should be changed(as is: nginx url rewrite -> no rewrite or cloudfront edge function, please refer to this document)

Further Work

• Healthcheck Endpoint Required
• Migrate mongoDB data to newly deployed mongoDB.
• deployment/base/server/secret-template.yaml using this template, change the according base64value and use kubeseal to update sealed-secret.yaml (https://www.notion.so/sparcs/K8S-Sealed-Secret-kubeseal-c3e315e429c442bebf8998b048404e17?pvs=4).
• deployment/base/server/configmap.yaml change the value of configmap variables accordingly.
• change the domain of ingress deployment/base/server/ingress.yaml after updating domain.
• Need to setup mongoDB backup job(This could be done by wheel members after discussion).
• Ingress routing rules should be changed accordingly(based on domain route rule decision)

Please Squash Merge this PR please!
🚀 LGTM :D
Wait until how domain routing rules would be changed
