metrics: Use StorageInfo() instead to have consistent info (#9006)

Browse Source 
Metrics used to have its own code to calculate offline disks.
StorageInfo() was avoided because it is an expensive operation
by sending calls to all nodes.

To make metrics & server info share the same code, a new
argument `local` is added to StorageInfo() so it will only
query local disks when needed.

Metrics now calls StorageInfo() as server info handler does
but with the local flag set to false.
