Update add-user utility to allow overrides of property file name.

This enhancement is going to add two additional command line options to the add-user utility: -

-up --user-properties

This will specify the file name of the properties file containing the users and passwords.

-gp --group-properties

This will specify the file name of the properties file containing the users groups.

If specified as absolute paths no searches will be used to locate additional file otherwise both the standalone and domain configuration folders will be searched for matching files.

group-properties can only be specified if there is a user-properties, the omission of group-properties will disable the prompt to ask for a users groups.

Specifying a user-properties disables the prompt asking if this is management or application as the primary reason for asking that was to decide which files to look for.
