Turning on node caching for a pool

Node caching is a feature for On-demand nodes that helps you dramatically speed up Docker builds and pulls, as well as pull time for large dependencies. When node caching is turned ON, nodes are paused between builds, rather than terminated. This means that any dependencies and Docker images remain on the node and only a delta will need to be pulled for successive jobs even if the dependencies change a bit.

Node caching is a premium feature that can be added on to any SKU. You can turn on node caching at a node pool level.
