Rewrite backend for remote 'volume inspect'

We need to use the new Inspect() endpoint instead of trying to
JSON the actual volume structs. Currently, the output seems
completely nonsensical; it seems like we're JSONing the struct
for the Varlink connection itself? This should restore sanity and
match the format of remote and local inspect on volumes.
