[Enhancement] Add configuration option to control log deletion

[abejenaru]

Hi, I have an use case where I can't have the users delete the log files themselves. Therefore I added a config option to control log deletion and changed the code accordingly.

Cheers, Andrei

BOOM! Your first PR with us, thank you so much! Someone will take a look at it shortly.

Please keep in mind that:

• if this constitutes a breaking change, it might take quite a while for this to get merged; we try to emulate the Laravel release cycle as much as possible, so developers can upgrade both software once; this means a new big release every ~6 months;
• even if it's a non-breaking change, it might take a few days/weeks for the PR to get merged; unless it's a no-brainer, we like to have some community feedback on new features, before we merge them; this leads to higher-quality code, in the end; we learnt this the hard way :-)
• not all PRs get merged; sometimes we just have to hold out new features, to keep the packages lean; sometimes we don't include features that only apply to niche use cases;
• we're not perfect; if you think we're wrong, call us out on it; but in a kind way :-) we all make mistakes, best we learn from them and build better software together;

Thank you!

I can totally see where this would be useful - thanks for taking the time to submit the PR @abejenaru !

Very nice & simple code, I tested it, works as expected 👏👏👏

Merging and tagging it right now - it'll be available with a composer update starting now.

Cheers!
