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.

Enhances the template engine and action config to allow users to inject custom template functions via an action config when using Helm as a library.

This change moves the code, updates the import locations, and
adds a doc.go file to document what the v2 package is for.
This is part of HIP 20 for v3 charts

chartutil was originally created to operate on protobufs which are
no longer part of Helm. The util package makes more sense to be
part of the chart package.
This change is part of the HIP 20 to create v3 charts and
explicitly call out v2 charts. The changes for this are in smaller
bite size changes.

Since Helm is going through breaking changes with Helm v4, the version path to
Helm needs to be updated.

This covers:
- `tpl` text can `include` a `define` provided in a partial file
- `tpl` text can `include` a `define` provided in its text
- `tpl` text can be loaded via `.Files.Get`

The templating engine handles errors originating from the `required` and
`fail` template functions specially, cleaning up the error messages to
be more presentable to users. Go's text/template package unfortunately
does not make this straightforward to implement. Despite
template.ExecError implementing Unwrap, the error value returned from
the template function cannot be retrieved using errors.As. The wrapped
error in ExecError is a pre-formatted error string with the template
function's error string interpolated in with the original error value
erased. Helm works around this limitation by delimiting the
template-supplied message and extracting the message out of the
ExecError string with a regex.
Fix the parsing of `required` and `fail` error messages containing
newlines by setting the regex flag to make `.` match newline characters.

This fixes#6044, in which error parsing is greedily eating too many
colons, preventing users from using colons in their warning messages to
the `required` function

Have updated the required filter so that it doesn't break when linting a
chart. This work is based off #4221 and #4748 which didn't make it into
the v3 branch.

Make template specific functions private to ensure they not misused and
make unit tests simpler. We may export the template helpers later if
needed.
This lays the foundation for the new chart pipeline.
