Remove requirement that host names are FQDN
We currently require that hostnames are FQDN not short names
(node1.example.com instead of node1). We can allow short names as long
as:
- we always resolve the names as returned by socket.gethostname()
- we rely on having a working resolver
These issues are not as big as may seem, as we only did gethostname() in
a few places in order to check for the master; we already required
working resolver all over the code for the other nodes names (and thus
requiring the same for the current node name is normal). The patch
moves some resolver calls from within execution path to the checking
path (which can abort without any problems). It is important that after
this patch is applied, no name resolving is called from the execution
path (LU.Exec() or other code that is called from within those methods)
as in this case we get much better code flow.
This patch also changes the functions for doing name lookups and
encapsulates all functionality in a single class.
The final change is that, by requiring working resolver at all times, we
can change the 'return None' into an exception and thus we don't have to
check manually each time; only some special cases will check
(ganeti-daemon and ganeti-watcher which are not covered by the
generalized exception handling in cli.py). The code is cleaner this way.

Fix the ssh change which breaks remote ssh commands
Explanation: since we use lists and not a string, every argument we give
is passed unchanged to the remote shell. So, for example, passing
'/etc/init.d/ganeti restart' to the remote shell, it will try to run the
path /etc/init.d/ganeti\ restart. With the s space included. This
breaks, for example, gnt-node add and gnt-cluster command.
The original problem with the backup routines that led to the "'" change
is that they use a plain " ".join(list), but we don't need to quote the
whole ssh remote command for this. We can simply use the existing
utils.ShellQuoteCmd(list) which does the proper quoting of the ';' or
'&&' metacharacters.
With this change, both gnt-node add, gnt-cluster command and
export/import work.
This also improves the error-handling behaviour of one cat command by
making it conditional on the preceding mkdir.

parameters and use the command line as returned in the script
- ssh.py, many changes, split options in module-level constants so
that building the command line in different places is easier/more
logical
- backend.py, we no longer remove root's known_hosts in Add node, and
we allow our own known_hosts file to be uploaded

Improve LURunClusterCommand
This function used a hand-coded ssh call to remote nodes. Fix it to use the
ssh.SSHCall function, and in the process drop the command field from the
results, as it's too verbose and we can use (in gnt-cluster) what we passed in.

Add information about installing from source.
In case one installs from source, make, tar and gzip are also needed. tar and
gzip are almost always installed, but make not, so let's add a note about that.
Also remove a '>' in the apt-get install example so copy-paste works.

In case we use StrictHostKeyChecking=ask, also add HashKnownHosts=no so that

Another documentation update.
This removes the section on packages from installing.sgml (until we have
packages) and adds/corrects informations about using the startup script.
It also adds notes about the ``--master-netdev`` option, which one needs
to use if the node doesn't have an interface named xen-br0 (or if it's
not the interface wanted for external access).

Style changes for pep-8 and python-3000 compliance.
This changes the raising of exceptions from:
raise Exception, value
to
raise Exception(value)
as the first form will be removed in python-3000 and the second form is
preferred now.
The changes also involve a few cases of changing from raising standard
exceptions and use our own ones.
The new version also fixes many pylint-generated warnings, especially in
ganeti-noded where I changed many methods to @staticmethod.
There is no functionality changed (barring any bugs).
