add ttl for raw client

[dmeijboom]

Based on #324 with the following additions:

• Rebased on tikv master
• Changed (KvPair, u64) to KvPairWithTTL

Seems like the clippy and integration test is failing.

Clippy makes sense:

Error: Unable to create clippy annotations! Reason: HttpError: Resource not accessible by integration
Warning: It seems that this Action is executed from the forked repository.
Warning: GitHub Actions are not allowed to create Check annotations, when executed for a forked repos. See https://github.com/actions-rs/clippy-check/issues/2 for details.

But for the integration tests I'll look into that

batch_put() api would give the following error:

gRPC error: RpcFailure: 13-INTERNAL Failed to deserialize response message: Codec(WireError(UnexpectedWireType(WireTypeLengthDelimited)))

tikv server: v6.1.3

I also tested tikv v4.0. It does not throw this error.

Example:

use tikv_client::{KvPair, RawClient};

#[tokio::main]
async fn main() -> Result<(), ()> {
    let client = RawClient::new(vec!["127.0.0.1:12379"], None).await.unwrap();
    let kvpair1: KvPair = KvPair("PD".to_owned().into(), "Go".to_owned().into());
    let kvpair2: KvPair = KvPair("TiKV".to_owned().into(), "Rust".to_owned().into());
    let pairs: Vec<KvPair> = vec![kvpair1, kvpair2];

    match client.batch_put(pairs).await {
        Ok(_) => println!("pairs are inserted"),
        Err(e) => println!("error: {}", e),
    };

    Ok(())
}

Output:

Dec 12 10:53:08.427 INFO connect to tikv endpoint: "127.0.0.1:20160"
error: gRPC error: RpcFailure: 13-INTERNAL Failed to deserialize response message: Codec(WireError(UnexpectedWireType(WireTypeLengthDelimited)))

Indeed, that was also my observation. I'm not sure what's going on and I don't have a lot of time to work on this. I'll try to get to the bottom of this in the next couple of days though. If anyone has any clues, please share ;)

just a wild guess. It may have something to do with the pb files. Let me also cross check the go client code to see if there is any finding.

Why removed put_ttl in #324?

[andylokandy]

Apologies for the delayed response. We have transitioned from grpc-cpp to tonic (#399), which should have resolved the issue in this PR. Regrettably, I do not have permission to merge this PR, so I will proceed with merging the previous one at #324. My apologies for any inconvenience caused.
