Research production hardened deployment of Melisearch

[scotwells]

Summary

Define our expectations for running a production hardened deployment of Meilisearch and determine what's possible (e.g. mTLS, High Availability, Network Policies, etc).

Acceptance Criteria

• Document production-hardened deployment options as part of the architecture documentation
• Confirm we can spin up a production-like deployment in a test environment
