Delete users plan_id users after admin-console functional tests

- Change from MiniTest::Unit.after_tests to teardown since the
  after_tests weren't being triggered properly, and users were getting
  created after every test run.  The 'unless @domain' doesn't skip the
  user creation on subsequent tests, so after the
  admin-console/test/functional/admin_console/api/search/users_contorller_test.rb
  script is run there are 7 users in the openshift_broker_test db with
  plan_id: "free".

Update get_quota to handle grace values

Update get_quota to support output from the `quota` command that
includes values in the grace columns. These columns have been empty for
ext4 volumes, but with xfs volumes, they can have a value, and that was
causing get_quota to return incorrect values for certain fields. Add the
-p flag to the quota call so the grace columns always have a value.

Fix bug 1129394.
