[Samba] Spotlight indexing with fscrawler for multiple shares

Hey Kees,

fs2es-indexer is designed to be a lightweight alternative to FSCrawler. 
So no ... it doesnt do any content indexing or saves much of the metadata.

As far as I understand it the OCR and other stuff makes FScrawler that 
big. And we dont need any of that - we just want to search for file names.

BUT Im open for merge requests ;-)

I currently getting away with a lot less complexity because I dont need 
to watch for changes in files. Because thats not something I'm indexing. 
If I'd be adding more metadata (even only size!) I have to verify that 
it stays correct and start to listen to "file X has changed" events 

fanotify seems like a sweet framework for that, but sadly ZFS is 
incompatible with it...

Samba does not let me get this data efficiently either, so Im forced to 
regular scans of the whole fs.... which might take a while depending on 
the amount of files.

Adding support for opensearch though shouldnt be that hard, right? I've 
already got a version switch for ES v7 and v8, adding OS to it should be 
easy enough!

Have a nice day,
