The new flag stops the parser from building arrays automatically when
top level elements are separated with commas. This flag converts parsing
into an actual no-op, passing through the input unmodified. This mode is
necessary when parsing values that may legitimately contain special
characters, like secrets.
This is the first step in fixing elastic/beats#29789. A follow up change in beats will follow to start ignoring commas when loading from the keystore.
Draft beats PR with a failing test that will pass with these changes: elastic/beats#31487
