    Fix race condition when changing node states

    To fix race condition we're adding a mechanism of background task
    execution in conductor. The conductor will get synchrozed AMQP call,
    reserve lock, start the background task and return empty response to
    the API. In case when lock cannot be acquired or background tasks pool
    is full, the exception is sent back to the API and the task is not
    started.

    Also the patch adds an ability to control resource locks manually.
    This feauture used to release lock in the end of background task.
