introduce new ServiceV2 API to handle guided restarts (#18826)

Browse Source 
New API now verifies any hung disks before restart/stop,
provides a 'per node' break down of the restart/stop results.

Provides also how many blocked syscalls are present on the
drives and what users must do about them.

Adds options to do pre-flight checks to provide information
to the user regarding any hung disks. Provides 'force' option
to forcibly attempt a restart() even with waiting syscalls
on the drives.
