Oleg Sidorov ec440d446d Replaced ghodss/yaml with sigs.k8s.io/yaml
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This change also resolves the outdated dependency version lock for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.
