Some charts don't need a templates directory. The warning appears to originate back when helm expected all charts to contain templates. In CI situations where linting is performed with --strict the lint warning causes unneccessary failures for charts that quite legitimately do not contain a templates directory.
As discussed in #8033 there are no longer any scenarios understood where this warning is helpful so this commit removes it.

First, some notes about priority and how some code flow works.
For Helm handling values, the expected order of precidence is:
1. User specified values (e.g CLI)
2. Imported values
3. Parent chart values
4. Subchart values
Helm handles dependency values slightly differently. If there are dependencies
in the charts folder that are not marked as dependencies all of the values,
including nil values, are pulled in. If those charts are listed as a
dependency in the Chart.yaml file than they are processed for import handling.
Prior to the changes here, it caused nil values at the top level to NOT remove
values specified.
The changes:
1. The order of priority was chagned from the list above. Parnet chart values
would override specifically imported values. This is due to a change from
just over a year ago that introduced a bug. That was undone by changing the
precidence when maps were merged.
2. To handle merging while retaining the nil values, which was causing
inconsistent behavior, a new set of Merge functions were introduced. These
functions are just like coalesce except that they DO NOT remove nil/null values.
The new functions are used in a backward compatible manner meaning some new
functions were introduced that called them.
Specific issues fixed (that are known):
Closes#9027
Can now delete subkeys from charts when specified in the parent. This behavior
was previously inconsistent. Sometimes they could be deleted and other times
it did not work. Now it is consistent.
Closes#10899
Imported values (from library or other subcharts) are now used following the
order above.
The previous behavior was inconsistent. import-values using just a string
would import them. When named with a child/parent it did not work if the
parent already had a value. If string and named were mixed the imports
worked if the string happened first but just for the string not the named.
If the named parent/child went first then none of them worked for cases
where the parent already had a value. It was inconsistent and the tests
sometimes mirrored the functionality rather than expected behavior.
Tests for this fall into the sub-packages and are in the template tests
to verify it's happening in the output. Including having values passed
at the CLI as the ultimate highest priority to be used.
This relates to a fix that went in for #9940. The expected values there don't
fit the precedence above where the parent value would override the imported
value. That fix/change introduced more bugs.
Closes#10052
This is the case where imported values using the parent/child designation
just didn't work right. That has been fixed and there are tests. The underlying
issue had to do with the precedence order handling.
Note, a lot of tests were added. Hope we got it more right this time.

When the engine stored templates in the map the keys were generated
based on path and not filepath. filepath was being used in the linter
when retrieving content from the keys. On Windows the keys ended up
being different.
This change is to use path joins to create the lookup key. Since the
name path was used in the code it needed to be changed in order to
import the package.
Tests already exist and were failing on windows. This got in because
CI is not run on Windows.

and an error if the chart contains `.Release.Time`. Further checks can be added

This commit replaces usage of github.com/ghodss/yaml with it's forked
version maintained by SIG community. The replaced library has
low-to-none support activity unlike the latter. We believe the new
Helm branch could benefit from using the community-supported version on
a long-term run as yaml parser is a key component of Helm chart rendering
engine.
This commit locks sigs.k8s.io/yaml dependency version on 1.1.0 which
is backwards compatible with ghodss/yaml 1.0.0.
This change also resolves the outdated dependency version lock for
ghodss/yaml (currently 1.0.0) and makes it possible to port changes from
https://github.com/helm/helm/pull/6010 to dev-v3.

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.
