Votable governance system for gas limits, block time etc.

[DogeProtocol]

Rationale

Using proof-of-stake consensus, a votable system is required for gas limits, block time etc.

Why should this feature exist?
What are the use-cases?

This will allow a governance model for the blockchain, instead of hard-coded parameters and also make it easier to make changes at runtime instead of a hard-fork or requiring client update.

However, post any new voted change, the system should allow a period of at-least 30 days, to give time for validators to update their hardware and network to keep up with gas limit changes.
