RequestContext.tenant and user fields are deprecated in favor
of project_id and user_id respectively.
This change modifies the glance.context.RequestContext constructor
to transition usage of tenant/user to project_id/user_id until
all tests are moved over to the new attributes. Runtime usage of
the old fiels is updated.
To prevent new code from using the deprecated fields, a warnings
filter is added which will make tests fail if they hit code using
the old fields.
