Added '--apt-conf' argument for ALTLinux template.

Added [-a|--apt-conf] parameter for selection of exact package

Sisyphus and 'apt-conf-branch' for the rest of branches.

new configuration keys

start: send state to legacy lxc-monitord state server even if no state clients registered

This pr https://github.com/lxc/lxc/pull/1618 kill lxc-monitord, for backwards compatibility,
we also send state to legacy lxc-monitord state server in function `lxc_set_state`.

we should also send state if there is no state clients registered, otherwise `lxc-monitor` client will
not get state change event if container changed state to `STARTING` or `RUNNING`.

lxc-monitord: exit when got a quit command

lxc-monitor has an option to tell lxc-monitord to quit.

```
~/lxc (master) # lxc-monitor --help
lxc-monitor monitors the state of the NAME container

Options :
  -n, --name=NAME   NAME of the container
                    NAME may be a regular expression
  -Q, --quit        tell lxc-monitord to quit
```
But it does not work. This patch fix that.
