[Improvement] UX warn users when disk space is low, stop processing

[pierotofy]

An upload will fail with a less useful "186 files cannot be uploaded. As a reminder, only images (.jpg, .png) and GCP files (.txt) can be uploaded. Try again." message, whereas the problem is lack of disk space.

Following on from this warning, would it be possible to have WebODM gracefully abort processing when disk space on the volume it is installed on drops to 10% free?

Something like that would have prevented the user here from filling their disk:

It might be possible to add this in NodeODM. I don't think it's as straightforward though (and is imperfect, since disk space might be fine during processing, but might fill past 100% when WebODM downloads a copy of the assets).

Yeah, that sounds like a tough thing to manage. Should I open an issue in NodeODM to track this?

I think we can include this in the scope of this existing issue (#615), so no need. Thanks!

Worst case scenario is when files can be uploaded, but when processing the files the disk is filled up (which crashes WebODM and prevents a user to delete any files without trying to access the VM manually).

Also, maybe you could add a hint to the installation guide on how to increase the VM Size. Because i spent 3 days trying to increase it until i found you can add --virtualbox-disk-size "300000" in C:\Program Files\Docker Toolbox\start.sh line 69

20GB default size is good for a test run, but allows no more then ~300 images

Big thanks to all of you for this nice peace of software!!!
