However, a miner does not have depicted their own mining block fullness.
We should also capture the block fullness of the miner. This way:
1) L1 miners can monitor their mining performance
2) L2 miners (who should also use prometheus/grafana) can monitor their mining performance
3) people working on optimizing the miner can run experiments that compare their performance to the baseline of what the network did
Describe the solution you'd like
Add analogous prometheus endpoints that we have for append block for the miner as well.
Is your feature request related to a problem? Please describe. Right now, we depict the block fullness of the last "accepted block" produced by the network. https://github.com/stacks-network/stacks-blockchain/blob/08c163bab484954b3934515ee7bf60848f52ed4a/src/monitoring/prometheus.rs#L94
