Delete 'default' security group associated to new projects.

OpenStack can create a security group named 'default' each time a
new project/tenant has been created but is not cleaned up when the
project has been deleted. This patch adds this functionality into
OpenStackProject#clean() method.

Also added similar routine to KeystoneUtilsTests#tearDown() method.

JIRA: SNAPS-169
