Fixed bug in how loggers were configured.
The program now takes care of creating host directories.

The destination directory should still exist though.
Example:
    Given the destination directory /root/var/backups and host A,
    if /root/var/backups exist, the program will create the directory
    /root/var/backups/A.
    If /root/var/backups does not exist (or is not accessible), the
    program will log an error and exit 1.
Fixed a bug config dump on debug logging level.
