[Implement KPIs] Implement Breadth of Coverage monitoring

[SamantaCasal]

Description:

Develop a metric that measures the percentage of coverage of known applications we process versus the total VAA issued. The metric should display a breakdown by application, and for those using more than one protocol, they should be disaggregated accordingly.

In this dashboard you can see a preliminary progress of the task. It shows:

• Total VAAs
• Total VAAs broken down by appID
• Number of unknown VAAs and their percentage
• VAAs by appID and VAAs by emitter chain

What remains to be resolved is that the new table being used is currently being populated and therefore lacks historical data.

I've added to dashboards: staging , prod-mainnet and prod-testnet , the following graphs:

1. total vaas
2. total unknown vaas
3. percentage of unknown vaas
4. time series of PORTAL_TOKEN_BRIDGE Vaas separated by the "secondary app_id" ( ETH_BRIDGE,CONNECT,etc)
5. time series of Vaas separated by main app_id ( app_id_1 )
6. time series of Vaas separated by appIds ( app_id_1 + app_id_2 )
7. time series of Vaas separated by emitter_chain

Graphs 4,5,6,7 are replicated in 3 granularities (5m,1h and 1d).
