Fix https://github.com/coreos/etcd/issues/7512.
If a server starts and aborts due to config error,
it is possible to get stuck in ReadyNotify waits.
This adds select case to get notified on stop channel.

Fix https://github.com/coreos/etcd/issues/7470.
This patch removes unnecessary term look-up in
'createMergedSnapshotMessage', which can trigger panic
if raft entry at etcdProgress.appliedi got compacted
by subsequent 'MsgSnap' messages--if a follower is
being (in this case, network latency spikes) slow, it
could receive subsequent 'MsgSnap' requests from leader.
etcd server-side 'applyAll' routine and raft's Ready
processing routine becomes asynchronous after raft
entries are persisted. And given that raft Ready routine
takes less time to finish, it is possible that second
'MsgSnap' is being handled, while the slow 'applyAll'
is still processing the first(old) 'MsgSnap'. Then raft
Ready routine can compact the log entries at future
index to 'applyAll'. That is how 'createMergedSnapshotMessage'
tried to look up raft term with outdated etcdProgress.appliedi.

If substream is closing but outc is still open while reconnecting, then outc
would only be closed once the watch client would connect or once the watch
client is closed. This was leading to deadlocks in the proxy tests. Instead,
close immediately if the context is canceled.
Fixes#7503
In cases of multiple endpoints, it's possible member add would get a its
member list from a member that has not yet recognized the membership
update. Instead, confirm that the member list response is from the
member that acked the member add or from a member that has synced
with the cluster following the member add.
Fixes#7498
If the context does not include auth information, get authinfo will
return a nil auth info and a nil error. This is then passed to
IsAdminPermitted, which would dereference the nil auth info.
Because of my own silly mistake, current NewAuthStore() doesn't
initialize authStore in a correct manner. For example, after recovery
from snapshot, it cannot revive the flag of enabled/disabled. This
commit fixes the problem.
