Create a Helm chart for deploying/running/configuring

[chadlwilson]

Context / Goal

It might be nice to have a simple Helm chart for running Recce that makes it easy to get up and running.

Need to decide whether we want to go down this route, but the chart could

• (Optionally) create a Postgres DB for recce itself (or possibly Cockroach - to be tested)
  • possibly use a sub-chart from Bitnami Postgres or CockroachDB
• install a single-instance Recce server
  • configure the server for connecting to the database automatically if installed

Expected Outcome

• TBC

Out of Scope
