Added optional TLS min/max protocol version and command line switches to set
versions for the etcd server.
If max version is not explicitly set by the user, let Go select the max
version which is currently TLSv1.3. Previously max version was set to TLSv1.2.

There is data race on `stop` channel. After verify write-timeout successfully,
the case won't wait for `blocker` to receive close signal from `stop` channel.
If the new `blocker`, which is to read-timeout verifier, get dial's result
immediately, the new `blocker` might fetch the message from `stop` channel
before old one and then close the connection, which causes that the
`conn.Read` returns `EOF` when it reads data.
How to reproduce this in linux devbox?
Use `taskset` to limit the test process in one-cpu.
```bash
cd ./client/pkg/transport
go test -c -o /tmp/test --race=true ./
taskset -c 0 /tmp/test -test.run TestWriteReadTimeoutListener -test.v -test.cpu 4 -test.count=10000 -test.failfast
```
To fix this, suggest to use seperate `stop` channel to prevent from data
race.

Only `net.TCPConn` supports `SetKeepAlive` and `SetKeepAlivePeriod`
by default, so if you want to warp multiple layers of net.Listener,
the `keepaliveListener` should be the one which is closest to the
original `net.Listener` implementation, namely `TCPListener`.
