Skip WatchRequestProgress test in grpc-proxy mode.

We shouldn't fail the grpc-server (completely) by a not implemented RPC. Failing whole server by remote request is anti-pattern and security risk. Refer to https://github.com/etcd-io/etcd/runs/7034342964?check_suite_focus=true#step:5:2284 ``` === RUN TestWatchRequestProgress/1-watcher panic: not implemented goroutine 83024 [running]: go.etcd.io/etcd/proxy/grpcproxy.(*watchProxyStream).recvLoop(0xc009232f00, 0x4a73e1, 0xc00e2406e0) /home/runner/work/etcd/etcd/proxy/grpcproxy/watch.go:265 +0xbf2 go.etcd.io/etcd/proxy/grpcproxy.(*watchProxy).Watch.func1(0xc0038a3bc0, 0xc009232f00) /home/runner/work/etcd/etcd/proxy/grpcproxy/watch.go:125 +0x70 created by go.etcd.io/etcd/proxy/grpcproxy.(*watchProxy).Watch /home/runner/work/etcd/etcd/proxy/grpcproxy/watch.go:123 +0x73b FAIL go.etcd.io/etcd/clientv3/integration 222.813s FAIL ``` Signed-off-by: Benjamin Wang <[email protected]>
