Allow the Confd client to be able to connect to an arbitrary server
instead of just the real one running on a cluster.

This is meant to be used for testing.

If a data collector using the Confd client is tested with shelltest, it will
need to receive through the CLI the address and port of the server, and also the
FQDN for which information is being requested. In normal usage it will likely be
the name of the node the data collector is running on, but for testing we need a
way to explicitly specify it so that it corresponds to the one used inside the
configuration files that the test confd server is reading.

So, optConfdAddr and optConfdPort and optNode are provided by this patch, even
if not used, because they are an important part of the modifications for making
the Confd client testable.

This commit expands the monitoring agent design document improving the
description of the general report file format.

There can be two kinds of data collectors (performance and status collectors).

Every collector can now be part of a category of collectors (such as
storage, instance, daemon, hypervisor, etc.) that defines a minimum basic
structure that has to be common to all the collectors part of the same class.

Also, such basic structure is defined for all the currently envisioned class

Until now if one disconnects a network with --no-conflicts-check
and then remove it, there is a possibility to leave instances with NICs
referencing non-existing networks. This causes network queries,
instance removal and modification to fail.

This patch allows a network to be disconnected from a nodegroup,
only if instances residing in the nodegroup do not have NICs attached
to the network. Otherwise OpPrereqError is raised. The
--no-conflicts-check option is removed from the gnt-network disconnect
command as well.
