Move deployment (terraform, helm, azure pipeline) to another repo

[geohacker]

The continuous deployment work that is underway in #1725 is currently tied to this repository along with the codebase. It will be good to make this a separate repo so that:

1. Builds are faster while debugging deploys
2. Less chances of accidental deploys
3. Easier to maintain application code and deployment code separately

This means that we will:

1. Move the deploy folder https://github.com/IFRCGo/go-api/tree/terraform/deploy to a new repo
2. Make the azure pipelines connection from this new repo
3. Test

Great idea!

Thanks @geohacker .

Yea, this was likely an error in judgement on my part: it seemed great and convenient to have it all in a single code-base. But as we've worked on it, it is increasingly seeming much more practical / easy to deal with if we split this up into a separate repository.

This is mostly for developer experience and convenience, it's not a blocker to the current work. So we should probably finish testing the whole setup with the current approach and then we can weigh the benefits and also work involved to split this out into a separate repository.

This is close to ready!

@sunu could you outline a checklist for next steps here and things we need to ensure as we do this move? Thanks!

Outlining the next steps below to move infrastructure code out of this repository to go-deploy repository:

• [x] Set up an Azure Pipeline for base infrastructure based on https://github.com/IFRCGo/go-deploy/blob/develop/base-infrastructure/azure-pipelines.yml
• [x] Double check the terraform resources in go-deploy and synchronize with the current state in this repo
• [x] Do a dry run that runs terraform plan against the staging cluster through the newly setup Azure pipeline
• [x] Merge https://github.com/IFRCGo/go-api/pull/2086 to build and publish helm charts
• [x] Synchronize the list of environment variables in the new Azure Pipeline for go-api to the current list of environment variables
• [x] Similarly, synchronize the list of environment variables being passed into the helm install command
• [x] Copy the current helm value files into https://github.com/IFRCGo/go-deploy/tree/develop/applications/go-api/helm/ifrcgo-helm
• [x] Create the new Azure Pipeline for deploying go-api in Azure Portal
• [x] Update the version to be deployed
• [x] Do a deployment test run for staging that runs helm with --dry-run flag
• [x] If everything goes fine, remove the --dry-run flag, change terraform plan to terraform apply and do a staging deployment
• [x] Repeat the same steps for production
