The basic scheduler has shown weakness when handling high load, which
manifests with the occasional deadlock situation. This introduces an
advanced scheduler, which contains additional features in an attempt to
ensure that regardless of the concurrent load no job is ever left in an
inconsistent state, explicitly with outstanding items to read on its
channels.
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.
The "best" aggregate attestation strategy obtains aggregate attestations
from all listed nodes, scores them according to their attestation
coverage, and signs and broadcasts the one with the highest coverage.
The "first" aggregate attestation strategy signs and broadcasts the
first aggregate attestation returned from all listed nodes.
