/**
 * Given the url of a service layer, get the layer info
 * and return the itemId, and the array of fields
 *
 * Make a request to the service layer url, and extract the `serviceItemId` property
 * from the response. If the service fails to respond, or does not have a
 * `serviceItemId`, this function will simply return isHosted: false without
 * and itemId.
 *
 * This is needed because although the webmap json *may* have an `itemId`
 * on a layer or table, there is no assurance that it is present or that
 * it reflects the actual service.
 *
 * Moreso - the `serviceItemId` in the getLayer response is indicative
 * of the layer being a hosted service, and thus something we are interested
 * and capable of templating
 *
