This allows callers to allocate a pseudo-TTY easily.

This renames some functions and does some minor codestyle cleanup.

Add function to write cluster SSH key to known_hosts file

The whole Ganeti cluster has a single SSH key. Its fingerprint is
written to Ganeti's known_hosts file, together with an alias. This
allows us to always use that alias instead of the real hostname,...

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
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...

Make import/export use the auxiliary ssh library to build the remote commands.

This avoids forgetting some parameters, as it's happening right now
(the correct known host file is not being passed)

In order to do so we split SSHCall into an auxiliary BuildSSHCmd which builds...

Rework ssh known-hosts handling.

This changes:
- cluster setup, we no longer edit /etc/ssh/ssh_known_hosts but our
own file
- node add, we no longer remove root's known_hosts (twice)
- gnt-instance console, both the LU and the script: since now the ssh...

Disable hashing of the ssh keys.

In case we use StrictHostKeyChecking=ask, also add HashKnownHosts=no so that
debugging is easier. The nodes to which we are connecting are anyway visible in
/etc/ssh/ssh_known_hosts.

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...
