1f0fb3d9aa etcdserver: forbid to unset v3 demo once used 
After enabling v3 demo, it may change the underlying data organization
for v3 store. So we forbid to unset --experimental-v3demo once it has
been used.

6974fc63ed etcdserver: avoid deadlock caused by adding members with wrong peer URLs 
Current membership changing functionality of etcd seems to have a
problem which can cause deadlock.

How to produce:
 1. construct N node cluster
 2. add N new nodes with etcdctl member add, without starting the new members

What happens:
After finishing add N nodes, a total number of the cluster becomes 2 *
N and a quorum number of the cluster becomes N + 1. It means
membership change requires at least N + 1 nodes because Raft treats
membership information in its log like other ordinal log append
requests.

Assume the peer URLs of the added nodes are wrong because of miss
operation or bugs in wrapping program which launch etcd. In such a
case, both of adding and removing members are impossible because the
quorum isn't preserved. Of course ordinal requests cannot be
served. The cluster would seem to be deadlock.

Of course, the best practice of adding new nodes is adding one node
and let the node start one by one. However, the effect of this problem
is so serious. I think preventing the problem forcibly would be
valuable.

Solution:
This patch lets etcd forbid adding a new node if the operation changes
quorum and the number of changed quorum is larger than a number of
running nodes. If etcd is launched with a newly added option
-strict-reconfig-check, the checking logic is activated. If the option
isn't passed, default behavior of reconfig is kept.
