Selectively disable sandboxing in FullDomFetcher

[Phyks]

Hi,

There is currently no way to easily overwrite the Puppeteer launch settings in fullDomFetcher. This means sandboxing is on and cannot be disabled. However, certain setups require to be able to disable sandboxing (e.g. Docker container).

In particular, some hosting providing Docker container support will not provide the ability to alter capabilities (--cap-add=SYS_ADMIN) which, AFAIK, is required for sandboxing to work (including when using a dedicated user).

See also #1001 (comment).

Maybe a good addition to cover all possible use cases would be to be able to selectively enable/disable sandboxing. I'm doing it at the moment by manually applying a patch on the codebase.

Thanks
