Fix the variable substitution

Prior to that commit if ceph_version was equal to 0.80.5, the variable
substitution ${ceph_version%.*} was returning 0.80 and not 0. Using
${ceph_version%%.*} returns the desired value.
Also refactoring the version output to get a X.X format since only
major and minor are important.

Remove TEMPEST_ENABLE_NOVA_XML_API from Tempest config

I5b3e221d942e09134024b82acaf179dc869357e0 has removed xml_api_v2 from
Tempest config, and xml_api_v2 setting of DevStack is unnecessary now.
This patch removes it.
