Create Baseline Storage Performance Tests

[willmeister]

In order to do #622, #623, and #624 and accurately determine whether or not an improvement was made, we'll need some form of baseline storage tests that:

• Build / reference a realistic (large) storage Trie
• Create a reproducible test suite that focuses on operations reading/writing from/to storage
• Outputs metrics that can be compared over time

This task is to find or create a test suite like this.
