clock sync
Change 24h and 1h to 30m and 10m respectively for clock sync. If a
storagenode's clock is off by more than 30m for every trusted satellite,
it will not start. If it is off by more than 10m for any trusted
satellite, a warning is displayed.

storagenode database preflight check.
Disable preflight database check by default, and have the option to
enable it. This will allow us to enable it once it is definitely
working.
Also change the name of the config flag for preflight time sync.
