* All this changes are temporary, they should be removed when
mysql module is updated
* add mysql_module parameter to provide backward compatibility
for mysql < 2.2
* disable rspec tests for openstacklib
* bind default value of mysql_module to '0.3' to avoid
changes in upstream modules
* added noop tests for mysql databases
It should fail noop tests and it's OK. It will start passing noop
tests for Openstacklib::Db::Mysql::Host_access only when we sync
all modules that use it with upstream.
