Helm CoalesceValues

// CoalesceValues coalesces all of the values in a chart (and its subcharts).
//
// Values are coalesced together using the following rules:
//
//	- Values in a higher level chart always override values in a lower-level
//		dependency chart
//	- Scalar values and arrays are replaced, maps are merged
//	- A chart has access to all of the variables for it, as well as all of
//		the values destined for its dependencies.
