Limit puppet-mysql module version from the top

Since mysql::python was deprecated by 01/01/2014
(see https://github.com/puppetlabs/puppetlabs-mysql/
commit/c22e72a97a4665a17178f358db72c73c3a5c70db)
all puppet modules' dependencies and spec's fixtures
relying on puppetlabs-mysql module/repo would fail, if
mysql::python is used as is in Fuel now, thus should be
fixed approrpiately, i.e.:
1) limit mysql dependencies in Modulefiles to <1.0.0
according to their upstream versions
(see https://bugs.launchpad.net/puppet-openstack/+bug/1271168)
2) add "ref:  'origin/0.x'" for mysql repos in .fixtures.yml

Closes-bug: #1270807
