Governance parameterization of rank window

[cyborgshead]

Note

With PR cosmos/cosmos-sdk#4206 now possible via governance change parameters values.

User Story:

Validators and users should adjust how faster rank recalculates, adapting the window for their needs and current hardware possibilities.

Task

Implement adjusting parameter CalculationPeriod via governance proposals, add validation for proposed values

Estimated workflow:

1. Handler: NewChangeRankCalculationWindowProposalHandler (decrease/increase)
2. Handler keeper: HandleChangeRankCalculationWindowProposal
3. Add given route to gov module in app.go
4. Add simple validation to the proposal (decrease/increase up to 2 times)
5. Solve potential issues on changing rank window with proposal online with local testnet

Definition of Done:

The rank window should be changed after a successful proposal (if validation of the proposed parameter's value passes) and network should calculate rank on block mod new rank window value

Example of proposal for spending from the community pool via governance proposal

{
  "title": "Community Pool Spend",
  "description": "Pay me some CYBs!",
  "recipient": "cyber1lecnk6rqq6hnvjmk4cmaec0utawj0agq5wdu8f",
  "amount": [
    {
      "denom": "cyb",
      "amount": "10000"
    }
  ],
  "deposit": [
    {
      "denom": "cyb",
      "amount": "10000"
    }
  ]
}
