Governance parameterization of bandwidth parameters

[cyborgshead]

Note

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

User Story:

Validators and users should can adjust grow of the network, adapting the whole bandwidth of network for their need and current hardware possibilities

Task

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

Estimated workflow:

1. Handler: NewChangeDesirableNetworkBandwidthProposalHandler (decrease/increase)
2. Handler keeper: HandleChangeDesirableNetworkBandwidthProposal
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 with meeter and bandwidth calculation

Definition of Done:

The bandwidth should be changed after a successful proposal (if validation of the proposed parameter's value passes) and network should allow cast more/less txs than it was before.

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"
    }
  ]
}
