[SERVICES-2600] Add Pair field for trades count in the past 24 hours

[mad2sm0key]

Reasoning

• front end requires information regarding pair swaps performed in the last 24 hours

Proposed Changes

• add tradesCount24h field to Pair model + resolver method
• refactor compute method for 'tradesCount' to use ESTransactions service
• add bulk get method and dataloader for the new field
• add new field to pair cache warmer
• add sorting and filtering by tradesCount24h to filteredPairs query

How to test

• Running the query below should return only the pairs with more than 30 trades performed in the last 24 hours

query  {
  filteredPairs(
    filters: {
      minTradesCount24h: 30
    }, 
    pagination: { first: 20 }, 
    sorting: {
    	sortField:TRADES_COUNT_24, 
    	sortOrder:DESC
    }
  ) {
    edges {
      cursor
      node {
        address
        firstToken { identifier }
        secondToken { identifier }
        tradesCount
        tradesCount24h
      }
    }
  }
}
