Attempts to eliminate some systemd unit cyclical dependencies (#181)

* Adjusts ordering and requirements for /cache mounts and formatting if the disk to avoid cyclical dependencies (caused by implicit dependencies).

* Makes format-cache.service depend on local-fs-pre.target to be sure that disk devices are available.

* Configures format-cache.service to start after dev-sda.device.

* Adds Requires=dev-sda.device to format-cache.service.

* Removes Requires=dev-sda.device to format-cache.service.

* Removes ordering and dependency statements from mounts and moves them all to format-cache.service, since that is the unit that needs to be treated in a non-default way.

* Tries relying solely on RequiresMountsFor.

* Removes RequiresMountsFor, and readds Before, and adds RequiredBy for various mounts.

* Moves RequiredBy to Install section, adds back DefaultDependencies=no.

* Adds brief comments about why we add certain dependencies and ordering.
