cli/create: remove path parsing and validation

Path parsing is now handled by libfile for the Azure File Service too,
so the CLI specific code can be removed.
This change removes some potentially useful location / affinity group
parameter validation code, but libfile currently only supports location
arguments, so it can go for now.
