Bug Description

repetitive_restart on snapshot #442 failed by OSTF failure

https://product-ci.infra.mirantis.net/job/9.x.system_test.ubuntu.repetitive_restart/106/console

https://github.com/openstack/fuel-ostf/blob/stable/mitaka/fuel_health/nmanager.py#L463

_delete_server method contains 20 sec timeout with 10 sec interval per retries, so only one validation retry is possible here. In case when instance is removing more than 11 seconds we are falling to error.
In test mentioned above I've analyzed nova logs and didn't found any errors related to instance deletion - it was actually removed properly so the solution is to bump timeout or reduce time between retries (I'm suggesting both changes)

    Modification of timeouts for server deletion

    Current timeout is 20 sec, and 10 sec retry period.
    In case slow instance removing we are falling to error.
    New intervals make procedure more correct to check real
    removing state few times.
