Remove compat

[longfangsong]

Signed-off-by: longfangsong longfangsong@icloud.com

Upgrade grpcio and remove the compaction code.

This should fix #148.

Note because of some dependency problems, we have to use my own fork of kvproto. And because of cargo #8258, we cannot use 1.43+ version of rust to build the project.
These limitations have been removed after these crates and tools are updated into new version.

This is great, thanks!

@sticnarf PTAL Do you think we can land this now or should wait kvproto to change? I'm not sure when that might happen.

[sticnarf]

Looks great.

@nrc
If TiKV changes to use futures 0.3, it's natural that kvproto upgrades its dependency. It's nice to have but it's not an urgent work. I don't expect it to happen very soon.

Anyway, instead of using @longfangsong's personal fork, can we add a branch using futures 0.3 to tikv/kvproto before landing this PR?

I prefer this solution too.

@longfangsong could you rebase this PR please? Do we have a branch on kvproto we can use?

I have a pr here: kvproto#633. But it hasn't get merged yet.
It seems I cannot create another branch in pingcap/kvproto, it needs write access of the repo.

[longfangsong]

Now we are using a branch on pingcap/kvproto.
So I think this pr is ready for merge.
