[Consensus] Suggestion about Sticky policy

[hyunsooda]

Among the three policies, Sticky policy is designed to anchor only one proposer. If this policy were to be not deprecated in the future, it would be beneficial to have a way to select a desired validator. If the Sticky policy is to be retained, it can be implemented based on the governance item rather than by adding a field to genesis.json, which would be overengineering.

The use case of the Sticky policy may vary depending on the desired purpose. In my case, specifically, this policy greatly reduces voting-related testing time. Say there are 100 validators and round-robin is used for proposer selection, when one validator votes, they have to wait for 100 seconds to insert the vote when they are supposed to generate a block in some round. This is quite time-consuming.
