Improved the retry mechanism of ``_cleanup_device_retry`` to account for active snapshots that take longer than expected to be removed, thereby preventing deletion errors. Updated the retry count based on trial and error. The maximum observed retries reached the 6th attempt, so we have set it to 6+1=7 retries.

Dell PowerMax Driver `bug #2092259
|
|
<https://bugs.launchpad.net/cinder/+bug/2092259>`_: Before
|
|
a volume can be deleted, the driver issues a command to clean up
|
|
active snapshots in the backend and then polls the backend
|
|
to make sure the cleanup has occurred.
|
|
This fix enhances the polling mechanism to give the backend
|
|
more time to do the cleanup, thereby increasing the probability
|
|
that the driver will be able to make a successful volume deletion
|
|
request.
