5.0 Add retry for volume test in rados sys test

in system tests for ceph rados gw we
call ostf as soon as deployment finish.
And sometimes test on vilume creation fails
with error status of volume.
Second retry to run test is succesfull.
It was caused by cinder scheduler,
when we run ostf it do not see available spaces for volumes.
So we add single run of volume test with retry and sleep in 60 second
And if it passed - we runs full ostf suits

Confirm disk re-partitioning before proceeding

Ask for a confirmation before Fuel installation on a drive with
existing partition table.

New kickstart kernel parameter:
  - "forceformat" - (yes/no) defaul is "no". Set to "yes" if you
                    want to format chosen drive automatically.

For example, if you add "installdrive=sda forceformat=yes" to the
kernel parameters line in Grub menu, then "sda" drive will be
formatted automatically and Fuel will be installed on it.
