openSUSE instructions for swift

Note that openSUSE uses openstack-swift as user/group

Change-Id: I89a9f71c7c63c28cdf1ebe2e738e0791b8b4e2fb
added password parameter for automated install

As requested for the use with Vagrant I added an ption to Keystone.sh
so it can be called with the mysql root password as a parameter.
The interactive option is still available if the script is called
without a parameter

Cleaned up some comments and prompts
