Subject: Allow launching with custom data directories (#1505)

* Allow launching with custom data directories

Don't load alternate keys when using custom directory

* Address gdkchan's comments

* Misc fixes to log levels

Added more enabled log levels by default

Moved successful config updation to Notice as
1. It's not a warning
2. Warnings could've been disabled by the config load and hence message
   would be lost
