Cleanup jenkins/jobs/projects.yaml

Move devstack-plugin-glusterfs, devstack-plugin-sheepdog and
drbd-devstack into stackforge section.

Remove cinder-salt-formula, designate-msdnsagent, glance-salt-formula,
horizon-salt-formula, keystone-salt-formula,  neutron-salt-formula,
nova-salt-formula, openstack-salt-formula, stacktach-*: these dummy entries are not needed.

Remove ec2-driver, milk, tricircle: zuul uses no jobs, so the
definitions are not needed.
