prometheus/metrics: three new metrics for consensus (#4263)
* prometheus/metrics: two new metrics for consensus - add consensus_validator_power metric so if a node is a validator it can see its own power in prometheus - add last_signed_height metric so if a node is a validator it can be aware of at which height the most recent time it signed. - closes: #3773 - closes: #3083 Signed-off-by: Marko Baricevic <marbar3778@yahoo.com> * check if signature is present * minor change and check if sig is not absent * add changelog entry * Update consensus/state.go Co-Authored-By: Anton Kaliaev <anton.kalyaev@gmail.com> * Update CHANGELOG_PENDING.md Co-Authored-By: Anton Kaliaev <anton.kalyaev@gmail.com> * Update CHANGELOG_PENDING.md * add label with validator address * change address to vali_address * add metric missed blocks * add changelog entry for missed blocks metric * address naming & add docs
