The manpage wrongly states that the default unit for disk sizes is
gibibytes, whereas currently it's mebibytes. Fix that and also update
the '--help' output to display the default unit.

- Run “gnt-cluster verify” and “gnt-cluster info” after adding all nodes
- Remove unused --cleanup option
- Remove --verbose option and always print executed SSH commands

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
    setup is not standard, we need to build the ssh cmdline in the LU
    (instead of manually building it in the script) with the correct
    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

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.

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

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).

It fixes the main Makefile.am to create $localstatedir/{lib,log}/ganeti.
It fixes the testing Makefile.am after the rename fake_config.py ->
mocks.py.  It strips the output of "ip link show" to have a nicer output
if the master netdev does not exist.
