Subject: [SERVER] Introduce autoFreeDiskSpaceDelay

This setting allows you to control the formerly hard-coded timeout of 10
hours before a proxy would start deleting old images in order to free up
space for new images. Setting it to -1 entirely disables automatic
deletion, in case you have an external process for freeing up disk
space.

+; When running in proxy mode and running out of space, automatically delete oldest image(s) to make
+; the newly replicated image fit. In sparse mode, this will make sure at least 2GB of free space are

+; as much space as is required to store the entire image will be made available.
+; However, after startup the proxy will refuse to delete any images for the time span given below, to be
+; able to gather up to date usage information for the images available. If unitless, the value is
+; interpreted in seconds. Valid suffixes are m, h, d.
+; Setting this to -1 disables deletion of images. If the cache partition is full, no more images will
+; be replicated unless you manually free up more disk space.
