[PATCH 0/3] Introducing get_alias method

[Jan Tluka]

Following patch set allows user to use aliases from a python task. This was
not possible before.

Example:

<lnstrecipe>
    <define>
        <alias name="virtual_ip" value="192.168.111.10/24"/>
    </define>

    <network>
        <host id="m1">
            <interfaces>
                <eth id="nic1" label="testnet"/>
            </interfaces>
        </host>
        <host id="m2">
            <interfaces>
                <eth id="nic1" label="testnet"/>
            </interfaces>
        </host>
    </network>

    <task python="my_task.py"/>
</lnstrecipe>

And the content of my_task.py:

from lnst.Controller.Task import ctl

virtual_ip = ctl.get_alias("virtual_ip")

m1 = ctl.get_host("m1")
m1.run("ip a add dev %s %s" % (m1.get_devname("nic1"), virtual_ip))

I've run regression check for the patch series without errors.

  XmlTemplates: do not drop toplevel aliases so that python task can see
    them
  NetTestController: adding get_alias method
  ControllerAPI: adding get_alias method to ControllerAPI
