> In many parts of our internal code, I would prefer we grab what we need
from AccumuloConfiguration, combine it with any additional configuration
appropriate for that specific context, and create a new context-specific
configuration object to pass around within that context.
Somehow get the RateLimiterFactory directly from the config? That'd be a
stop-gap.

Yeah, I totally understand. Finding some middle ground to avoid lots of
unrelated changes to your actual feature is ideal.
