Generate analytics vaa metric

[gipsh]

Based on the VAA we need to generate a metric on influxdb and populate the data.
The analytics componen will be in charge of this new metric called vaa.

The vaa metric contains the serialized information from the VAA and also metadata like token symbol and notional value
in the moment the vaa was created.

The vaa metric should include those tags:

• origin_chain --> solana/eth/etc
• detination_chain --> idem
• token --> symbol like ETH/wETH/1SOL/etc
• origin_address --> address of the ECR-20 on the origin_chain
• destination_address --> destination wallet

The vaa metric should include those fields:

• amount --> amount of the asset transfered
• notional --> price of the asset when the vaa was created
• v = amount * notional

This is an example of a generated metric on line protocol fomat:

vaa,origin_chain=solana,target_chain=bsc,token=ETH,origin_address=solana,target_address=000000000000000000000000808522060e36128fc3ae58ca2f2789b5a4444444 amount=2.600000,notional=1.2341 1634633931000000000

For this metric to be generated we need:

• A token resolver --> from a chain + token_address returns the symbol and decimals. Token resolver #281
• Notional fetcher --> based on the symbol returns the current price Notional asset lookup #223

The workflow should be like this:

1. Analytics receives a VAA
2. Decode it and increment the VAA count metric
3. Decodes de payload. If is not a portal payload returns.
4. Try to find the symbol using the resolver.
5. If its avalid symbol then tries to fetch the notional
6. Push the data to influx
