vmagent: expose metric vmagent_remotewrite_queues (#2871)
The new metric `vmagent_remotewrite_queues` exports a static value of number of configured remote write queus. This metric is useful to calculate total saturation per each configured URL with given number of queues. See corresponding changes to vmagent alerts and dashboard.
