Opencue should support different logging paths for Windows and Linux

[DiegoTavares]

Is your feature request related to a problem? Please describe. Users running rqd on both Windows and Linux have no way to define different paths for windows and linux.

Ideas for implementation

1. Simplest: log.frame-log-root in opencue.properties could be replaced by 2 entries, one for Linux and other for Windows (log.frame-log-root.windows, 'log.frame-log-root.linux`)
2. Recommented: Accept multiplelog.frame-log-root.[OS], where OS relates with str_os on the job table

In my opinion, 2 is preferable and will not require that many changes. Mostly getJobLogDir and getJobLogPath on JobLogUtil.py

Option (2) here sounds like a great solution. 👍
