celebrating orgs with full time maintainers

### Problem Statement
hiring and retaining full time maintainers (those who are contributing at 75% or higher of their time) should be celebrated because it's hard for managers and businesses to justify this kind of contribution.

### Proposed Solutions
- add a page on k8s.dev/orgs with company logos who currently employ full time OWNERs to areas of Kubernetes
- add booth signage to companies who meet this criteria at kubecon/cloudnative cons (thanks to @eddiezane for this idea and adding some in Detroit!)

### Cost
n/a; professional signage could have a cost for #2 or we could allow companies to do their own

### Open Questions
- [ ] How do we know for sure that someone is full time on the project? [possible solution: add names and/or handles publicly or privately, community moderation, private emails to steering@, steering reviews on a yearly basis as part of annual reports, etc]

### Next Steps
- [ ] discuss at an upcoming steering committee meeting
- [ ] PR a prototype into the k8s.dev website repo

Start by reviewing the proposal for a new page on k8s.dev/orgs and the open question of how full-time maintainers would be verified. Discuss the criteria at a steering committee meeting before exploring a prototype in the k8s.dev website repository. Done means an agreed verification process and a reviewed prototype for the page and related signage.
