CONF.task.task_time_to_live doesn't work

[wangxiyuan]

Reproduce:

1.set task_time_to_live to 1 in glance-api.conf:
    task_time_to_live = 1

2. restart glance-api

3. create a import task
{
    "type":"import",
    "input":{
        "import_from":"http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img",
        "import_from_format":"",
        "image_properties":{
            "disk_format":"qcow2",
            "container_format":"bare",
            "name":"test-task"
        }
    }
}

4. wait for task success

5. show the task:
     glance task-show xxxx

Expect : updated_at and expires_at should have the difference of 1 hours.
Actual : they have the difference of 48 hours, which is the default value of task_time_to_live.

The reason is that taskflow created a task object , different from the one created by the glance api. And the task_time_to_live was set to default 48 when taskflow get it.

    Make task_time_to_live work

    CONF.task.task_time_to_live doesn't work now. When change it's value,
    the task's properity 'expires_at' and 'updated_at' still have the
    difference of 48 hours.

    The reason is that taskflow create a new task object and doesn't use
    the task_time_to_live which glance api passed before.
