Feature Gate: Update Hashes per Tick 3

None

Description

We need to ramp up required hashes per tick to keep validators busier based on analysis in https://docs.google.com/spreadsheets/d/1NDJZiSFxqbVIi0jn-7I7MrYN2lqP4j9GePZdyPZ1fhI/edit#gid=1060803070

https://github.com/solana-labs/solana/pull/33600 Adds several discrete values to ramp up the required hashes per tick as these features get activated.

All nodes need to adopt the same hashes per tick at the same time otherwise we will see consensus mismatches due to differing block hashes.

Single Core Contributor

Deployment Considerations

PoH sleep/hash rate metrics will need to be monitored to ensure analysis on achievable hashes per second and hashes per tick continues to hold up.

The feature is effectively done. Plan is to enable these features (for which I hold the key) to slowly increase required number of hashes while ensuring majority of the cluster can still keep up. Features are currently included in v1.17.2. We've discussed backporting to v1.16.x
