Is your feature request related to a problem? Please describe.
Right now the client doesn't offer the possibility to disable the cache entirely.
We do our own caching in the consumer of the resolver and we don't want to double caching.

Describe the solution you'd like
A way to turn off caching and disable the moka dependency.

Describe alternatives you've considered

Let hickory do the caching. This is fine for some cases, but we do a mix of hickory and os name resolution so we need to implement our own caching.
Simpler/dumb caching mechanism, moka is a big dependency with lots of moving parts that ideally we would want to avoid in general. There are simpler libraries for caching out there, specially if we do cache eviction in hickory.

If this is something you are willing to consider @djc I can push the implementation.
