webproject: Do not disable existing loggers

Change default settings for logging, to not disable existing loggers by
default. This was already done for the API, but not for 'snf-manage'.
Also, the example conf file were not updated.

helpdesk: Change logging level

Change logging level of messages about unauthorized access to helpdesk.
Info level should be enough.

snf_django: Log exceptions to 'django.request'

Change api_method decorator to log unhandled exception in
'django.request' handler in order to match with Django's default
behaviour to log unhandled exceptions as 'error' in 'django.request' and
sent mail to admins for such cases.

astakos: Cache visible resources in GET /quotas

Speed up GET /quotas by caching the list of API visible resources.
For consistency, apply the cache in GET /resources, too.

snf_django: Propper logging of unexpected errors

Extend logging of unexpected errors, in 'api_method' decorator to
include the request and the status code in the log record, in order to
be properly displayed by Django's AdminMailHandler.
