[price-service] Fine-tune metrics (#401)
- Remove nodejs default metrics. We don't use them. - Remove response time metric. - Remove freshness metric and add gap metric for attestationTime and publishTime. They are similar; however, freshness was measured upon user request but gap is measured upon receiving the next update. - Change receivedVaa to actually represent distinct vaa received. Prior to this, the older vaas, or vaas with same attestation time were not counted in this metric. This will also improve the performance. - Refactors the code a little. `vaaBytes` type was not string and was Buffer. It is fixed now.
