add graph for rank and stake share

[shrimalmadhur]

• Rank in Quorums based on your TVL. This can help setup an alert where for ex - if you are ranked almost last by TVL, you can get churned out
• Stake share in Quorums - in Basis Points
• Signing %age - One caveat is that since this metrics comes from node, it doesn't have information if our disperser is able to reach your node or not. But this will tell you if you received and not signed a batch

# HELP node_registered_quorums_rank the rank of operator by TVL in that quorum (1 being the highest)
# TYPE node_registered_quorums_rank gauge

node_registered_quorums_rank{quorum="1"}
# HELP node_registered_quorums_stake_share the stake share of operator in basis points in that quorum
# TYPE node_registered_quorums_stake_share gauge
