Configuring Voyage Linux with Ansible

Connect to voyage linux installs over SSH. This requires running the remountrw
command before and the remountro command after to make the filesystem writable
for the duration of the command.
Use a little meta-programming, and the decorator pattern to provide a thin
layer over the existing SSH connection plugin.
The `remountro` command is only issued when a persistent connection is closed,
but in most cases this won't matter as issuing it is just an attempt to clean
up after ourselves - voyage has a cronjob that does this periodically.
Check out the source of the SSH connection plugin here:
NOTE: This plugin does not have support for the `sudoable` argument that may
be passed in when doing exec_command on a connection plugin.

return super(Connection, self).put_file(*args, **kwargs)
def close(self, *args, **kwargs):
return super(Connection, self).close(*args, **kwargs)
