…ber of samples it tracks. The number of samples to track is computed in proportion to the number of accounts and blocks in the ledger. This will scale the throttle over time as ledger size adjusts.

Adds ability for the bootstrap throttle to dynamically change the number of samples it tracks.
The issue with using a fixed number is it doesn't scale as the ledger scales and particularly causes high CPU usage in unit tests or prematurely stops bootstrapping with the live ledger.
This change dynamically changes the number of tracked samples as the ledger grows.
The formula used for selecting the throttle size is config.throttle_coefficient * sqrt(block_count) and the throttle coefficient uses a default value of 16 which is a good fit based on beta and live testing.
