As protobuf doesn't have required field, user may send an empty
WatchRequest by mistake. Currently, etcd will ignore the invalid request
and keep the stream opening. If we don't reject the invalid request by
closing the stream, it would be better to leave a log there.
This commit also fixes a typo in the comment.

To verify distributed tracing feature is correctly setup, this PR adds
an integration test for this feature.
In the process of writing the test, I discovered a goroutine leak due to
the TraceProvider not being closed. This PR fixs this issue as well.

Problem: We pass grpc context down to applier in readonly serializable txn.
This context can be cancelled for example due to timeout.
This will trigger panic inside applyTxn
Solution: Only panic for transactions with write operations

The `ErrFileNotFound` was used for for three cases:
1. There is no any WAL files (probably due to no read permission);
2. There is no WAL files matching the snapshot index;
3. The WAL file seqs do not increase continuously.
It's not good for debug when users see the `ErrFileNotFound` error,
so in this PR, a different error is returned for each case above.

`Poll` means that the elements in the heap will be removed.
And it is more appropriate to use `Peek` to get the top of the heap.

The default max stream is 250 in http2. When there are more then
250 streams, the client side may be blocked until some previous
streams are released. So we need to support configuring a larger
`MaxConcurrentStreams`.

There is no update on the original PR (see below) for more then 2
weeks. So Benjamin(@ahrtr) continues to work on the PR. The first
step is to rebase the PR, because there are lots of conflicts with
the main branch.
The change to go.mod and go.sum reverted, because they are not needed.
The e2e test cases are also reverted, because they are not correct.
