Fix race condition that was causing dangling loop devices
...
Apparently it is wrong to assume that `DeleteVolume` gets called
only after `UnstageVolume` returns success. This was causing the
disk image file to be deleted while the volume was still mounted.
This would prevent the loop device from getting detached and in
turn disk space from getting reclaimed.

Increase controller's timeout to prevent retry loops
...
Since remote tasks might get a bit longer to get scheduled, it's
reasonable to increase this timeout. Specifically, we faced an
issue with a `DeleteVolume` action timing out over and over since
it was running a bit over the default timeout.

btrfs: Change default subvol upon creation
...
The default root subvol comes with its own limitations and it might be
better off changing the default subvol upon creation. This should also
let us create hidden subvols that may be used for storing snapshots,
without exposing them to the end-user.

btrfs: Mount with `flushoncommit` flag
...
Not an expert on this, but my understanding is that without this flag,
outages will result in a state that despite being consistent, most
applications are not mature enough to handle. Namely, we ran benchmarks
that reproduced appearance of zero-length files upon sudden poweroffs.
Databases should be fine since they know well about the guarantees the
filesystem must provide, but not applications are databases. So let's
play safe about this.

ext4: Do not reserve free space for root user upon creation
...
PVCs are data volumes most of the times, and reserving space for system
tasks is probably unnecessary.
The user can still modify a specific PVC's reserved blocks through the
