* remove suspend cache
This PR replaces suspend cahce usages w/ direct guava cache usage.
I think we should also get rid of guava cache.
First of all it is in java so needs to be moved to kotlin at least for
future multi-platform support.
Second, it would be nicer to have something that uses kotlin's time so
that people can provide a scope w/ a delay functionality (like the
TestCoroutineScope) and also test time related stuff. An alternative might
be letting people pass a Timer in the builder
Fixes#41

It uses guava's cache under the hood and handles query deduplication in a custom
