[SERVICES-2457] Extra fields on Pair model for previous 24h data (fees, volume, liquidity)

[mad2sm0key]

Reasoning

• compute and display % change over the past 24 hours for pair volume, fees and liquidity

Proposed Changes

• add fields and resolvers on Pair model : previous24hLockedValueUSD, previous24hVolumeUSD, previous24hFeesUSD
• add compute methods and caching for new fields

How to test

query {
  filteredPairs(
    filters:{
    }
    pagination:{
      first:200
    }
    sorting: {
      sortField:TRADES_COUNT
      sortOrder:DESC
    }
  ) {
    edges {
      cursor
      node {
        address
        firstToken {
          identifier
        }
        secondToken {
          identifier
        }
        feesUSD24h
        previous24hFeesUSD
        volumeUSD24h
        previous24hVolumeUSD
        lockedValueUSD
       	previous24hLockedValueUSD
      }
    }
    pageInfo {
      startCursor
      endCursor
    }
    pageData {
      count
      limit
      offset
    }
  }
}
