Finish refactoring of provider/network statistic

[stalniy]

Why

Currently provider statistic is aggregate per type (e.g., activeStats, pendingStats) and it makes it harder to work with this data structure. It's harder to pass all needed details for one entry. For example, to display (or to work with) CPU/GPU related information I need the whole Provider because their stat values are in 3 different objects.

That's why I'd like to change how it's aggregated, better to aggregate per metric and then each metric has all needed values inside. Additionally, this helps to manage changes because if we want to remove metric - we remove it from single place (not in many other objects). If we want to add metric, it's also easy

What

New stats object:

type newStats = {
  cpu: {
     available: number;
     pending: number;
     active: number;
  };
  gpu: {
     available: number;
     pending: number;
     active: number;
  };
  // etc
}

Currently used stats object:

type currentlyUsedOne = {
  activeStats: {
     cpu: number;
     gpu: number;
     // ....
  };
  pendingStats: {
     cpu: number;
     gpu: number;
     // ....
  };
  availableStats: : {
     cpu: number;
     gpu: number;
     // ....
  };
}

DO NOT remove the previous ones immediately, because some people may use cached version of console-web. Keep old values in place for a week or so

Acceptance

• /network-capacity route should change response to match new structure
• /providers/{address} should expose new stats property that adheres to the new shape above
• /providers should expose new stats property that adheres to the new shape above
• remove old fields
