CNCF Annual Review of Carvel as a Sandbox Project

Sandbox projects are subject to an annual review by the TOC. This is intended to be a lightweight process to ensure that projects are on track, and getting the support they need. Process [outlined here](https://github.com/cncf/toc/blob/main/process/sandbox-annual-review.md#how-to-file-your-annual-review).

Your annual review should answer the following questions:

- [ ] Include a link to your project’s devstats page. We will be looking for signs of consistent or increasing contribution activity. Please feel free to add commentary to add colour to the numbers and graphs we will see on devstats.
---------> https://carvel.devstats.cncf.io/d/8/dashboards?orgId=1&refresh=15m
- [ ] How many maintainers do you have, and which organisations are they from? (Feel free to link to an existing MAINTAINERS file if appropriate.)
---------> 10 (9 VMware, 1 converge.io) https://github.com/carvel-dev/carvel/blob/develop/MAINTAINERS.md
- [ ] What do you know about adoption, and how has this changed since your last review / since you joined Sandbox? If you can list companies that are adopters of your project, please do so. (Feel free to link to an existing ADOPTERS file if appropriate. Refer to the [FAQs](https://github.com/cncf/toc/blob/main/FAQ.md#what-is-the-definition-of-an-adopter) for more information on adopters.)
---------> Based on our conversation at KubeCon in Amsterdam, those that attend our community meetings, and those that contribute to the project, as well as those that add their details to our [pinned issue](https://github.com/carvel-dev/carvel/issues/213) and [adopters file](https://github.com/carvel-dev/carvel/blob/develop/ADOPTERS.md), we have several adopters, including Swisscom and bol.com, which we met in Amsterdam.
- [ ] How has the project performed against its goals since the last review? (We won't penalize you if your goals changed for good reasons.)
- [ ] What are the current goals of the project? For example, are you working on major new features? Or are you concentrating on adoption or documentation?
- [ ] How can the CNCF help you achieve your upcoming goals?
- [ ] Do you think that your project meets the [criteria for incubation](https://github.com/cncf/toc/blob/main/process/graduation_criteria.md#incubating-stage)?

Start with the CNCF sandbox annual review process linked in the issue, then compare the existing answers with the 2022 Antrea example. Check MAINTAINERS.md, ADOPTERS.md, the devstats dashboard, and pinned issue #213 for supporting information. Done means all annual-review questions are answered, including project performance, current goals, CNCF support, and incubation criteria.
