[Examples] add a new example of tabby

[sunny0826]

Add a Tabby example to guide users in quickly deploying Tabby on any cloud using SkyPilot.

Thanks for the exciting demo!!! 🚀 Tried the YAML and it works great 💪🏻. Left several nits ;)
Also, a discussion: There is a lot of introduction content for the skypilot repository, which seems a little bit redundant inside the skypilot repo. Maybe we could remove some of them? cc @Michaelvll for a look 👀

nit: example of tabbyml -> example of tabby

Thanks for the PR! ❤️

@cblmemo Sorry for the somewhat late reply, I've been attending KubeCon China for the last few days. I fixed and tested most of what was in the review feedback.

Unfortunately, I found a bug in my testing: when I opened the port with ports: 8080, the record 8080 was not added to the network security group created by skypilot, which prevented me from accessing Tabby via public IP. After I manually added port 8080, Tabby was able to access it properly.

I haven't read the source code, so I'm not sure if this phenomenon is unique to Azure or if all clouds have similar issues.

Additional context

• cloud: Azure
• region australiaeast

Thanks for reporting that! I tried this YAML with accelerators: V100:1 commented out (due to quota issues) several times, and one of them failed. It seems like an occasional happened bug. Will dive deep into it 🫡

Thanks for adding this tabby example @sunny0826! This is fantastic! Left a question for the toml file. Otherwise, LGTM.

[wsxiaoys]
