Production deploy setup

[zwolf]

• Nearly everything Eras needs to deploy to production. Deploys via production-release tag as usual. Includes startup/liveness probes and adds them for staging.
• Took a wild guess about resource utilization--staging is minuscule but prod is gonna be getting the kinesis firehose.
• Database migrates on deploy via a job, if it's unsuccessful the deploy will halt.
• Removes tag deploy for lambda, these are both now manual deploys (workflow dispatches) only and environment specific. Both prod and staging use the same function, which is deployed to two different lambdas with different endpoints.

The prod TS database still needs to be created pending confirmation of tier. New lambda has been created and needs to be deployed and connected to the prod kinesis trigger.

I created the database and also the production credentials file with db & kinesis creds in it. I stored the new production master key in a kubernetes secret. Also added the production db migration job, which will run on deploy after the image build/push and before the k8s deploy.
