oslo_context.Context.from_environ provides a more generic way to contruct a context object from request environment. We can support more new attributes supported in keystonemiddleware without changing our code. Partial-Bug: #1674349 Closes-Bug: #1621073 In the unit test, context.tenant_name is replaced to context.project_name as it will be the recommended way to access project name now. Note that equivalency of project_name and tenant_name will be ensured by a depending neutron-lib patch [1], so this change affects nobody.
