Throttle getstoragestats.php calls and allow simultaneous uploads

Improves speed on #13854 and #13696. Does not address reliability in any way.

Tested and works nicely 👍 Also the getStorageStats call on every upload is not there anymore. Nice finding 💯

Looks good 👍

Cool 👍

limitConcurrentUploads: 10 if you select 10 files a 50mb they are uploaded in parallel. not sure if this is a sensible default. i would vote for a lower value (e.g. 4).

@danielkesselberg but but but what if I upload 100 tiny files? Then 10 concurrent will probably be faster 😉

This heavily depends on your uplink, server speed and filesize. I believe one could justify just about any value. I did my tests on a pcengines apu2c4 with about 5MB files and I was still far from reaching the link speed (got 10Mbit/s).

Ok if this is a reasonable standard that works for most of your users.

Why not make this an admin setting that we can set in the webGUI as an admin to tune it for our setup? I mean, hiding the setting seems like asking for trouble. Yes? :)
