Removing functionalnosetests

With the Icehouse release of openstack-swift functional
case classified as fucntionalnose tests have been moved
to functional cases.Although we copied test suites from
test/fucntionalnose/ to test/functional/ but we still
have same cases under test/functionalnose.This might
cause duplicate tests run.
