    Remove deprecated attributes from context

    The oslo.context emits a warning for attributes that are not listed in
    [1] and considered to be deprecated. According to the warning message,
    the policy file should be modified to use $(project_id)s instead of
    $(tenant_id)s. Also, context.user is deprecated. We should remove lines
    using context.user and use context.user_id only.

    The following deprecation warnings are gone with the patch:

    - context.py:100: DeprecationWarning: Policy enforcement is depending on
      the value of tenant_id. This key is deprecated. Please update your
      policy file to use the standard policy values.

    - test_auth.py:75: DeprecationWarning: Property ‘user’ has moved to
      ‘user_id’ in version ‘2.6’ and will be removed in version ‘3.0’
