Linting is specific to the chart versions. A v2 and v3 chart will
lint differently.
To accomplish this, packages like engine need to be able to handle
different chart versions. This was accomplished by some changes:
1. The introduction of a Charter interface for charts
2. The ChartAccessor which is able to accept a chart and then
provide access to its data via an interface. There is an
interface, factory, and implementation for each version of
chart.
3. Common packages were moved to a common and util packages.
Due to some package loops, there are 2 packages which may
get some consolidation in the future.
The new interfaces provide the foundation to move the actions
and cmd packages to be able to handle multiple apiVersions of
charts.

This is part of HIP 20 which provides a means to have v3 charts
that live alongside v2 charts while having breaking changes.
The plan is to have a different release object for v3 chart
instances for at least a couple reasons:
1. So that the chart object on the release can be fundamentally
different.
2. So that Helm v3 does not detect or try to work with instances
of charts whose apiVersion it does not know about.
Note: it is expected that Helm v3 usage will be used long after
the Helm project no longer supports it. 5 years after Helm v2
had reached end-of-life there was still usage of it.
Note: The release util package is separate from the versioned
elements as it is planned to use generics to handle multiple
release object versions.
