Dev Task: Redis - include as part of deployment

Describe the task We want a fully deterministic process for deploying and maintaining redis, so we need to create a template and deploy as part of some pipeline.

Acceptance Criteria

• Templates in source control
• Instructions + script for deploying
• ??? Part of pipeline? If so - which pipeline? Which product?

Additional context

• Redis is used extensively by various process in wps. The current redis deployment configuration being used was manually created in openshift 3.* use the service catalogue. In 4.* the equivalent process would be to use helm developer catalogue to create a deployment.
• We could have multiple applications/projects using redis. e.g. wps-api uses redis, cronjobs, tileservers etc. etc. we need to consider - do we need one redis server? many? do we just have a template that we manually run? do we include it as part of the pipeline?
