Warning Mode

[cawoodm]

Is your feature request related to a problem? Please describe.
It can be risky to activate API validation on existing APIs and it would be nice to have a "warningMode: true" option to not block invalid requests but only log warnings about the URL and issue.

Describe the solution you'd like
When warningMode: true the system does not block requires but logs URL and reason.

Describe alternatives you've considered
ignorePaths does not meet our requirement

Additional context
Would perhaps be nice to enable this feature by path / regex.
