YAML size limit issues due to snakeyaml 1.33

Issue Description:

On Upgrading to 14.7.13, latest 15 versions there is an exception on deploy, which is related to org.yaml/snakeyaml upgrade

Caused by: org.yaml.snakeyaml.error.YAMLException: The incoming YAML document exceeds the limit: 3145728 code points

Issue Analysis:

This is caused due to snakeyaml being upgraded to v1.33 in the newer versions due to security issues.

Since v1.32 of snakeyaml, the max size for yaml was decreased to 3MB: https://bitbucket.org/snakeyaml/snakeyaml/commits/440d98e2ebd586aafd9034fc74a2a47c656eb0ce

Current workaround:

Manually splitting YAML from one big parent to multiple smaller files

Expected Resolution:

We need to either relax the limit or have a documentation to explain the the problem and the workaround (or both).
