Spec Lite: Deprecate owner_is_tenant

Spec Lite: Deprecate owner_is_tenant

project:

glance

problem:

The owner_is_tenant option, which is True by default, allows an operator to run Glance in a nonstandard configuration where the image owner is the user who created the image. In all other OpenStack services, resources are owned by the project (as they are in Glance when the default setting is used).

A survey of operators conducted in March 2017 indicated that no operators who responded (14) are using this option. As it is little used, results in a nonstandard OpenStack experience, and complicates the Glance code, the option should be deprecated in Rocky. Following the standard OpenStack deprecation policy, it should be removed early in the ‘S’ cycle.

solution:

Use the oslo.config facilities to mark the option as deprecated. As it appears that this option is used only in its default setting of True, no migration path is proposed.

impacts:

None
