Reflection warnings

[raszi]

First of all, thank you for the library!

We can still see some reflection warnings using your library:

Reflection warning, diehard/rate_limiter.clj:34:9 - call to static method sleep on java.lang.Thread can't be resolved (argument types: unknown).
Reflection warning, diehard/rate_limiter.clj:45:13 - call to static method sleep on java.lang.Thread can't be resolved (argument types: unknown).
Reflection warning, diehard/circuit_breaker.clj:78:3 - reference to field allowsExecution on dev.failsafe.CircuitBreaker can't be resolved.
Reflection warning, diehard/core.clj:62:39 - reference to field getConfig can't be resolved.
Reflection warning, diehard/core.clj:83:11 - call to method withBackoff on dev.failsafe.RetryPolicyBuilder can't be resolved (argument types: java.lang.Object, java.lang.Object, java.time.temporal.ChronoUnit).

I believe it would be a good idea to add a call to (set! *warn-on-reflection* true) in the test suite or something like that to avoid regressions.

We used to have this global option in lein config. Now in deps.edn there is no alternative way to do so.
