ConcurrentBloomInterval

[apfitzge]

Problem

• Want to do earlier filtering for keys we know to not pay fees

Summary of Changes

• ConcurrentBloomInterval - will be used to store invalid fee paying keys and filter them out quickly. These keys should be reset periodically, so wrapped in an AtomicInterval so that only 1 thread actually does the clearing.
• Eventually, I'm hoping to use this in both sigverify and banking stage, so wanted to define the struct somewhere both perf and core can use it.
