use finalized block stream

track metric from finalized blocks instead of latest blocks to handle possible reorgs which can screw up the metrics otherwise

General improvements

• support sol endpoints with api key
• improve logs -> numbers are logged without the commas
• initialize some metrics to 0 at startup

Add new metrics

• add cf_block_weight
• add cf_price_delta/cf_quote_unavailable for solana

Switch to gauges

Use gauges instead of counters to avoid edge cases regarding the increment of a counter in case the exporter restarts.

Solana metrics

Added solana metrics:

• aggKey balance
• config account balance
• durable nonces monitoring (available/unavailable nonces, check that nonces match both on-chain and on the state-chain)
• rotation metric -> check that the rotation tx is successfull and didn't revert on-chain

Fix bug with Validator metrics

Fixed a bug which was preventing to specify more than 10 validator to monitor in the configuration

Monitoring RPCs

With this release we changed the way the exporter collects information about the network:

• At the protocol level we introduced some RPCs which provide access to the internal data so that we can avoid relying on the storage items reads directly

Improve logging + dot_agg_key_balance metric

• Added state-chain block height to the logs
• Added aggKey address as label to dot_agg_key_balance
