feat(cache): organization (#8903)

# Which Problems Are Solved

Organizations are ofter searched for by ID or primary domain. This
results in many redundant queries, resulting in a performance impact.

# How the Problems Are Solved

Cache Organizaion objects by ID and primary domain.

# Additional Changes

- Adjust integration test config to use all types of cache.
- Adjust integration test lifetimes so the pruner has something to do
while the tests run.

# Additional Context

- Closes #8865
- After #8902
