Add a proper testsuite about hashbrown HOT 4 OPEN

https://github.com/jakubadamw/arbitrary-model-tests is an evolved version of https://github.com/blt/bughunt-rust - it autogenerates all the verification code in a proc macro, all you have to do is supply it with a reference implementation of the data structure to compare against. It already includes a HashMap example using std::HashMap.

Which is basically hashbrown :p Finding a way to integrate it here would be amazing though! And I'll see if I can't take a stab at getting it set up with griddle too.

@jonhoo, I'm the maintainer of that project (which now has a proper name: rutenspitz), so if I could be of any assistance, please do cc me. :)

In the past I have used it to fuzz hashbrown, which is how I found the issue #113. It was however deemed the expected behavior. 🙂 The fuzzer could nonetheless be used as part of a regression suite, perhaps.

I've adapted indexmap's tests/quick.rs for the standard HashMap interface over in https://github.com/jonhoo/griddle/blob/master/tests/quick.rs, which may also be helpful. My plan is to try and keep the two synced, while adding some additions that are specific to the standard HashMap.
