[PATCH 2/4] nodewatcher: Output to stderr instead of log file

[Fabian Bläse]

Maintaining a logfile manually is complicated and
has no major improvements over just logging to stderr,
because nodewatcher is no deamon and can be run manually
for debugging purposes.

Also, the debug output from subscripts currently is not
written to the log file anyway and the debug level is not
used eiher.

Therefore, the file logging and debug level is removed
from nodewatcher, which simplifies the code a bit.
