Mixins: draw graphs at full resolution

Remove "intervalFactor: 2", which corresponded to "Resolution 1/2" in
the Grafana UI. This feature has now been dropped from the UI, and I
can't see why were ever using it - why would you not want the full
resolution for your panels?

Left `awx-mixin/dashboards/clustertable.libsonnet` untouched because
those are table queries not timeseries.
