Zhi Yan Liu 6aa9dd1ec8 Remove incubative openstack.common.context module
glance_store library needn't to use openstack.common.context
module really, the only relevancy is swift store unit test, which
would be better to use mock instead however.

The patch changed swift store unit test to use mock easily,
and removed glance_store.openstack namespace due to context
module is the last one incubative module synced from oslo-inc.
We might use graduated oslo library in future neatly and hopefully.
