feat: live switch avax quote for 100 percent

[jsy1218]

We check the following metrics before we decide to increase traffic switch on AVAX:

• Is AVAX still sampling at 10%, meanwhile live traffic switched at 1%?
  Based on the metrics, this appears to be the same:

• Is the success rate on the AVAX endpoint and on each AVAX RPC call consistent?
  AVAX endpoint shows the consistently high success rate:

• Is the latency on the AVAX endpoint consistent?
  AVAX latency does not change after live switch:

• Is the RPC call volume only slightly up after quote shadow sampling on AVAX?
  AVAX RPC call volume only shows minimum increase, which is important because when we live switch, we don't expect to see any further more RPC calls due to our optimized implementations:

• Is the quote accuracy always 100% between new v3 quoter and current v3 quoter?
  The accuracy comparison shows it's always at 100%:
