Use oslo.context class method to construct context object

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.
