* Don't always pull smartctl data it's slow on old disks * Cache data for 2 minutes * Force updates if disks change on the system
* Error handling in our ustorage, to prevent crashes * Small change to ubnt-fw-parse so it works better on older python versions
* Write a mock ustorage tool to parse disk info for ulcmd * Pass system temp info from unvr-fan-daemon to mock-ubnt-api via tmp file * add mock ubnt-tools to make ulcmd happy and report our SN * code cleanup and documentation update
