[oslo] Proposing Lance Bragstad as oslo.cache core

Hello everybody, It is my pleasure to propose Lance Bragstad (lbragstad) as a new member of the oslo.core core team. Lance has been a big contributor to the project and is known as a walking version of the Keystone documentation, which happens to be one of the biggest consumers of oslo.cache. Obviously we think he'd make a good addition to the core team. If there are no objections, I'll make that happen in a week. Thanks. -- Moisés Guimarães Software Engineer Red Hat <https://www.redhat.com> <https://red.ht/sig>
