Subject: [ruby/logger] Changes to datetime formatting

Formatting a datetime should only pertain to itself and valid datetimes do not contain a space. Should there be a desire to show show a space between the datetime and the process pid in the formatted log, this formatting logic should take place there.
Furthermore, the default datetime format is moved to a class variable to allowing this variable to be overwritten by subclasses.
