`options(options, callback)`
----------------------------
Normalize options. An ssh connection is needed if the key "ssh" 
hold a configuration object. The 'uid' and 'gid' fields will 
be converted to integer if they match a username or a group.   

`callback`          Received parameters are:   

*   `err`           Error object if any.   
*   `options`       Sanitized options.
