DisableExec flag

[pjdufour-truss]

The DisableExec can be used to disable execution of exec("....") within fizz files, such as during syntax validation. This is simple approach and preferable to a regex replace approach.

Default behavior is preserved and the only new public function is NewBubblerWithDisabledExec.

To be honest, I think there is a real issue in the way the exec function is processed. It's not because of you, but thanks to your contribution I can see the problem better now: while most of the functions are just translating fizz statements to their equivalent in SQL (so the SQL query is not executed right now), the exec command is processed while parsing the fizz contents.

That behavior is not correct, since you can expect to execute a SQL command, then execute an external command depending on this SQL; but the exec statement is processed before anything else.

We should rework and fix that so everything is processed in the correct order, so I'm afraid you're trying to patch the wrong thing. :)

Thank you very much for the response and explanation. I'm new to pop/fizz and don't fully understand its architecture, so I think I'd have to leave it to an expert to make that significant improvement. Could we create an issue where this can be tracked until resolution?

So what's the way forward for this request? Merge this PR and add TODO? Or do you see a fix in the near term? Linting fizz files is a key developer experience improvement. Thanks for your thoughts.
