Re-implement accountmanager metrics. This reintroduces prometheus metrics for the account manager module. The metrics track the validating state of each account, and are found under the `vouch_accountmanager_accounts_total` metric. The metrics are differentiated using the `state` label. 2020-12-16 05:46:00 -08:00			`Development:`
Add `vouch_ready` and `vouch_release` metrics. `vouch_ready` is a prometheus metric that is `0` if Vouch is not yet ready to validate, and `1` if it is. `vouch_release` has a labeled value `version` that contains the release version of Vouch. 2021-02-01 11:27:06 -08:00			- provide release metric in `vouch_release`
			- provide ready metric in `vouch_ready`
Handle chain reorganisations. When a chain reorganisation occurs it is possible that this impacts Vouch's attestations and proposals for the current and next epoch. This patch listens to the Ethereum 2 events stream for reorganisation notifications. If it finds one it cancels existing and creates new duties, as required. 2021-01-31 05:49:15 -08:00			`- handle chain reorganisations, updating duties as appropriate`
Add `controller.max-attestation-delay` This option allows users to control the maximum amount of time that Vouch will wait for a block to arrive before starting its attestation process. Note that this is a spec value, so changes can have a highly detrimental impact on Vouch's behaviour. 2020-12-30 15:12:05 -08:00			- add `controller.max_attestation_delay` option

Fix 'vouch_attestation_process_duration_seconds'. This metric used to count the number of internal attestation processes carried out, however a single attestation process can involve multiple validators if they are attesting in the same slot and committee. This fix ensures that the metrics reflect the number of attestations, not the number of processes. 2020-12-16 06:05:11 -08:00			`- metric 'vouch_attestation_process_duration_seconds' now counts multiple attestations correctly`
