From Dispatching containers to cloud VMs

• (counter) cumulative instance time and cost, partitioned by allocation state and node type

In principle, these metrics can be estimated based on the existing instances_total and instances_price metrics. However:

• prometheus doesn't offer an integral function
• updating a cumulative metric after every worker/pool update (i.e., in updateMetrics()) would provide decent accuracy even when prometheus sampling is infrequent/unreliable.
