Svelte front end, Kubernetes and optional Vault integration

Release notes

I have not published a new release for a while, so figured it is a good time for an update. Since release 0.4.0 (several months ago) and in descending order of implementation from newest to oldest:

• Optional integration with Hashicorp Vault when running in Kubernetes for static credentials management (Feb 2021). See ./vault for details
• Migration from go-Micro to Micro
• Setup application to run in Kubernetes
• Creation of Svelte based front end
