There were errors for 32bit vs 64 bit stuff, and didn't think it was important to change. I can look into it if you're concerned though

What this PR does / why we need it: There was an issue with FeatureStore.get_historical_features when you pass records with timestamp with non-UTC time zones (pandas merge_asof was throwing an exception). This PR fixes that issue by converting all timestamps in the entity to UTC. If timestamp is tz-naive, we assume it's UTC. If it's tz-aware, we localize to UTC.
I also made significant changes to the tests. First, when generating entities we now generate timestamps in all kinds of different formats. Second,
test_historical_retrieval.py:get_expected_training_dffunction used a very similar logic to the local offline store (based on pandas merge_asof). Meaning that if there are bugs in the local offline store, we replicate them in the test. Instead of adding the identical logic to this test, I rewrote this method to do manual (non-pandas) join. This should give us more confidence in the offline store correctness.Which issue(s) this PR fixes:
