The dynamic time-series bucket calculation, from , decides to artificially lower the maximum size of buckets based on two relatively unchangeable characteristics - WT cache size & bucket cardinality.

For some workloads, the pre-configured slope between limits may not be desirable, as it assumes keeping all buckets in memory will suit their needs. Add a server parameter to influence or directly control this calculation so that a customer can adjust the sliding window between bounds to fit their scenario better. Allowing the constant factor of 2 to be adjustable OR simply adding a constant (defaulted to 1) to the front would allow a customer to adjust the slope of the calculation between min and max.
