[SERVICES-2577] Staking farms filter by depleted rewards

[mad2sm0key]

Reasoning

• The front-end needs a way to filter out staking farms with depleted rewards on the filteredStakingFarms query

Proposed Changes

• add rewardsDepleted boolean filter to filteredStakingFarms query

How to test

• the query below should only return staking farms with remaining rewards

query {
  filteredStakingFarms(
    filters:{
      rewardsDepleted: false
    }
    pagination:{
      first:1
    }
    sorting: {
      sortField: TVL
      sortOrder: DESC
    }
  ) {
    edges {
      cursor
      node {
        address
        apr
        farmingToken {
          identifier
        }
        farmToken {
          ticker
        }
      }
    }
    pageData {
      count
      limit
      offset
    }
  }
}
