tor_DataDir is a bad var name since it is not related to tor's DataDirectory

Lets rename it to "tor_parent_DataDir".

Sound reasonably, since there is one main tor user and instance users. So there can be distinction between:

• tor_InstanceDataDir
• tor_ParentDataDir

Also adding to this I see there is already discrepancy in naming conventions of variables (camel case vs snake case). It would be nice to refactor it into one coding style.

tor_ParentDataDir -> lets go with "tor_DataDirsFolder" (the folder that contains all tor DataDirs)
