Tasks from plugins of version 1 and 2 are not executed

[Georgy Kibardin]

unless propagate_task_deploy attribute is set to true. The problem is that there is no any warning about that.

Step to reproduce:
1. Take https://github.com/openstack/fuel-plugins/tree/master/examples/fuel_plugin_example_v2 as a base
2. Add shell task with "touch /task_has_been_launched" with role '*'
3. Build and install the plugin
4. Perform deployment
5. check /task_has_been_launched file on nodes

Expected:
  File exists
Actual:
  No such file

We've discussed a topic and decided the following:
1. Make propagate_task_deploy flag accessible from UI.
2. Add a property to plugins indicating presence of legacy tasks.
3. In UI disallow enabling plugins with legacy tasks unless propagate_task_deploy is on (with appropriate indication of why it cannot be enabled).

    Disallow enbling a plugin with legacy tasks

    When plugin contains legacy tasks enabling it makes no effect unless
    propagate_task_deploy attribute is set. The plugin silently does
    nothing. In order to avoid confusion enabling is prohibited explicitly.
