Frontend Continuous Deployment

[adamkendis]

Fixes #656

AWS changes

• Working URL for dev site: dev.311-data.org
• New Cloudfront distribution for dev site.
• Added ALIAS record in Route53 to point dev.311-data.org to new Cloudfront distribution.
• Added Cloudfront permissions to dev-deploy IAM user so the Cloudfront cache can be invalidated on each dev/prod deploy. I can't imagine we'll ever hit the 1000 free invalidation paths/month limit.
• Updated dev and prod S3 bucket permissions.

New Secrets

S3_BUCKET_DEV
S3_BUCKET_PROD
CDN_DISTRIBUTION_ID_DEV
CDN_DISTRIBUTION_ID_PROD
SERVER_URL_DEV  ->   EC2 instance

Workflows

• Removed github-pages deployment from workflows.
• CI/CD workflows for dev and production.
  • Builds the project and syncs dist directory to corresponding S3 bucket.
  • Creates invalidation for corresponding Cloudfront distribution.

Looks good!

I was wondering whether we need to run the tests in these workflows, since we're already running them when there's a pull request. But I guess it doesn't matter since the tests aren't really doing anything right now anyway.

Yeah, you're right. Running the tests is pointless in the new workflows. I'll pull it out.
