Get caching working

[jacebenson]

This ... needs to work for... lambda deployments where you have ~10s to execute.

To get caching to work we need to update gitpod's yaml to set up a redis host.
Update the prisma setup to use the caching for properties and messages.

This is the first step to getting rules to work as database entries.

• Add redis caching
• When a property or message is created, updated or deleted, reset the cache
• Open a new issue to build a table for rules
