Maintainess issue of pprof-rs

[Xuanwo]

Maybe when he is not that tired, he'd like to contact someone who knows the community rule of the tikv to help him solve the problem.

Based on my knowledge, only tikv committers can push tags directly.

Possible solutions include as follows:

• Inviting one of the committers to take care of this project, maybe @andylokandy? They don't need to take part in the development, just need to push tags for release. I think it's not a big burden since pprof-rs is not heavy traffic.
• Ping one of tikv's maintainers to give you more rights on this project. Because it doesn't make sense that you are the maintainer of pprof-rs but don't have permission to push tags.
• Transfer this project out of tikv's umbrella if the tikv community doesn't have an interest in maintaining it.

Also, ping @tisonkun for more advice about the current situation.

Databend depends heavily on pprof-rs and I'm interested in maintaining pprof-rs, we can help maintain this project.
