It's to deflake TestAuthMemberRemove.
When the client has multiple endpoints, the client might send a request
with valid token to the follower member which hasn't received token
replicated log yet. The member will reject the request.
For instance, the maintenance.Status API will return "auth: invalid auth
token". But the client doesn't identify the error. The client won't retry to
refresh auth token. The maintenance.Status should togRPCError before return
so that the client can reflesh token. It's align with existing API.
Since the maintenance client always creates one connection to target
member, the member will have the token after refresh auth.
Maybe we can introduce a sync to wait for member is ready with token,
instead of refreshing.

Progress notifications requested using ProgressRequest were sent
directly using the ctrlStream, which means that they could race
against watch responses in the watchStream.
This would especially happen when the stream was not synced - e.g. if
you requested a progress notification on a freshly created unsynced
watcher, the notification would typically arrive indicating a revision
for which not all watch responses had been sent.
This changes the behaviour so that v3rpc always goes through the watch
stream, using a new RequestProgressAll function that closely matches
the behaviour of the v3rpc code - i.e.
1. Generate a message with WatchId -1, indicating the revision for
*all* watchers in the stream
2. Guarantee that a response is (eventually) sent
The latter might require us to defer the response until all watchers
are synced, which is likely as it should be. Note that we do *not*
guarantee that the number of progress notifications matches the number
of requests, only that eventually at least one gets sent.

This commit makes the rarely used `raftpb.Message.Snapshot` field nullable.
In doing so, it reduces the memory size of a `raftpb.Message` message from
264 bytes to 128 bytes — a 52% reduction in size.
While this commit does not change the protobuf encoding, it does change
how that encoding is used. `(gogoproto.nullable) = false` instruct the
generated proto marshaling logic to always encode a value for the field,
even if that value is empty. `(gogoproto.nullable) = true` instructs the
generated proto marshaling logic to omit an encoded value for the field
if the field is nil.
This raises compatibility concerns in both directions. Messages encoded
by new binary versions without a `Snapshot` field will be decoded as an
empty field by old binary versions. In other words, old binary versions
can't tell the difference. However, messages encoded by old binary versions
with an empty Snapshot field will be decoded as a non-nil, empty field by
new binary versions. As a result, new binary versions need to be prepared
to handle such messages.
While Message.Snapshot is not intentionally part of the external interface
of this library, it was possible for users of the library to access it and
manipulate it. As such, this change may be considered a breaking change.

All maintenance APIs require admin privilege when auth is enabled,
otherwise, the request will be rejected. If auth isn't enabled,
then no such requirement any more.

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.
