We'll need a cache layer for person ID and person properties. Maybe also for groups, but we can toss that up for later.

We'll be using Redis for this (unless a very strong reason comes up down the line to not do so).

What needs to be done:

• Create a separate database in Redis to host this data for logical separation
• Implement the usage of this cache on the plugin server (getting, setting, TTLs)

The cache needs to account for:

• Person properties
• Person ID
• Person created_at
• Group properties
