Issue:
Track blinded/unblinded block building from the BN
# 🎯 Problem to be solved

Local blocks will get bigger and bigger. It's important to track when peers build local blocks, as this will require higher bandwidth between the cluster peers. 

# 🛠️ Proposed solution

Add a metric to track if the block built was blinded or not. Note that we don't want that for the block that will be proposed, but the one fetched from each peer. This way we will get more visibility for each peer on each block build.

Add panel to our grafana as well.
