Change SshRunner usage

Currently the SshRunner uses a SimpleConfigReader instance, however this
is not best. We change it to use the cluster name directly (and its
constructor now takes this as parameter, instead of SCR), and its
callers are change to pass the name directly....

Move SSH option building into a function

I'm going to add another option and it would make maintaining

SshRunner.Run: Pass all arguments to BuildCmd

This patch changes SshRunner.Run to pass all arguments to
SshRunner.BuildCmd. They had the same arguments before
and should stay that way. This change makes it easier
to add new or change existing arguments.

Fix adding pristine nodes

If a node hasn't been part of the cluster before being added it'll not
have the cluster's SSH key. This patch makes sure to accept those by
not aliasing the machine name to the cluster name.

The whole Ganeti cluster has a single SSH key. Its fingerprint is

Replace more ssh paths with proper constants

The node's ssh keys filenames are now provided as constants; this should
allow easier customization.

Also, the user's ssh key computing has been abstracted into ssh.py

Remove the shebang from modules

Since modules are not directly executables, remove the shebang from
them. This helps with lintian warnings.

Also make the autogenerated _autoconf.py contain two comment lines at
the beginning, like the other modules.

Fix the ssh change which breaks remote ssh commands

Explanation: since we use lists and not a string, every argument we give

This avoids forgetting some parameters, as it's happening right now

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