Make the server log level more configurable, not defaulting to debug.

This disables debug output in the Apache log by default. If you want
increased output create /etc/ipa/server.conf and set it to:

[global]
debug=True

If this is too much output you can select verbose output instead:

[global]
debug=False
verbose=True
