Rework QA interaction with the watcher

The interaction with cron-launched watcher is a well-known failure mode of QA:

---- 2010-10-14 06:54:55.464839 time=0:00:56.764827 Test tools/move-instance

For the following tests it's recommended to turn off the ganeti-watcher cronjob....

Add a new watcher option --ignore-pause

During cluster maintenance, when the watcher is disabled, it's useful to
run it just once. This is incovenient to do currently, as the watcher
needs to be unpaused, then run, then paused again.

This patch adds an option “--ignore-pause” that can be used to ignore...

Fix compatibility with Pyinotify 0.8

I didn't know why the code previously used
“pyinotify.EventsCodes.ALL_FLAGS” instead of using the flags from
“pyinotify.EventsCodes” directly. Turns out that Pyinotify 0.8 has them
in “pyinotify”, not “pyinotify.EventsCodes”....

ganeti-rapi: Watch directory, not file for user file changes

We noticed several issues when just watching the file, among them race
conditions upon replacing the file using rename(2) (the new watcher
would be created too soon). By just watching the directory for events on...

Extract base class from SingleFileEventHandler

The base class can contain code useful to other inotify users.
As it is “SingleFileEventHandler” can not be used in ganeti-rapi,
therefore it'll use its own small inotify handler class based
on this base class....

Move the parameter types to their own module

This is for cleanup, and for later reuse in other parts of the code
(outside of LUs).

"Fix" handling of old software versions on startup

Currently, masterd startup with old software versions is very confusing
for users: we present two tracebacks, with a message in the middle about
"version mismatch". This can lead to users believing that all that needs...

Export more information via LUQueryInstances/RAPI

Currently, the custom instance parameters (hv, be, nicp) are only
queryable via LUQueryInstanceData. LUQueryInstance returns only the
filled parameters, thus its users (especially RAPI) have no way to know...

Show instance state in instance console failures
