Move SimpleConfigReader creation to ConfdProcessor

This will be useful to make ConfdProcessor aware of a config failure,
without quitting confd.

ConfdProcessor: add disabled state

This is a state the processor will get in, if it fails to load the
config.

confd: s/confd_event_handler/inotify_handler/

In a case we don't encounter frequently (file modified but not
overwritten) the notify handler we use is called with a wrong name.

Implement timers in confd

Timers are used both for checking for inotify failures, and for polling,
should inotify notices become too frequent.

ConfdInotifyEventHandler.enable: use InotifyError

Rather than raising ConfdFatalError directly
ConfdInotifyEventHandler.enable raises InotifyError should it not be
able to configure inotify, allowing the caller to decide what to do.

ConfdInotifyEventHandler, move to a callback

ConfdInotifyEventHandler used to reload the config whenever a
notification arrived. Moving to a callback system, so that
ConfdConfigurationReloader can be responsible for that functionality.

Additionally the inotify class no longer reenables itself automatically,...

Move creation of inotify handler to a new class

This class will be responsible for managing inotify notifications,
timers, and rate-limiting reloads. For now none of these features is
implemented. :)

ConfdInotifyEventHandler: add enable/disable

Make possible to enable and disable the inotify event handler. The
inotify handler will remain enabled, unless explicitely told to disable
itself.

Convert ganeti-confd to Mainloop

Now that mainloop is asyncore-enabled we can easily do that.

Remove unused imports from confd files

confd.server and daemons/ganeti-confd import a few modules they don't
actually use. Clean them up.

Initial confd implementation

ganeti-confd is a simple asynchronous daemon, which listens on a UDP
port, passes each packet to a processor, and sends back to the client
the result.

It also listens on an inotify socket, in order to reload its
configuration when the ganeti config file changes....
