Preserve user-typed YAML after save

[eric-anderton-at-rearc]

I would like to request that the system preserve whatever the user types in to a YAML field. Right now, Noop strips the original formatting and comments from what I type in for Pipeline Condition and Workflow fields.

The strongest use cases I can provide for this:

• I like to use comments to "turn off" code when trying things out
• Comments help describe what is actually going on in the code
• Comments also provide needed guideposts for future maintenance
• Not everyone agrees on how to represent sequences and hashes in YAML (e.g. [one, two, three] vs dashes)
• Indentation preferences may differ between users and organizations
