With the addition of quota preallocation throttling, we want to support a general algorithm that considers the maximum allowable prealloc size and recommended shift modifier from various sources (i.e., global fs state and all applicable quotas for an inode). Update the current global free space throttle algorithm to cap the preallocation size to the free space available in the filesystem.
