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: start in polling mode

This allows us not to enable the inotify handler immediately, and thus
to make it easier for us should the config file not exist at all.

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....
