aef55342d1 etcdsever: avoid creating member dir before finishing validate bootstrap 
This commit fixes the issue of creating member dir before validating
the configuration. When member dir exists, it indicates the local etcd
process is a valid etcd member. So we should only create member dir
after we finish configuration validation, joining validation or
discovery validation.

> math/rand is unrelated to crypto/rand; the latter reads from /dev/urandom and

a46ffc60e5 client: add a mechanism for various endpoint selection mode 
Current etcd client library chooses a default destination node from
every member of a cluster in a random manner. However, requests of
write and read (for consistent results) need to be forwarded to the
leader node as the nature of Raft algorithm. If the chosen node is a
follower, additional network traffic will be caused by the forwarding
from follower to leader.

Mainly for reducing the forward traffic, this commit adds a new
mechanism for various endpoint selection mode to the client library
which can be configured with client.Config.SelectionMode.

Currently, two modes are provided:
 - EndpointSelectionRandom: default, same to existing behavior (pick
   a node in a random manner)
 - EndpointSelectionPrioritizeLeader: prioritize leader, for the above
   purpose

I evaluated the effectiveness of the EndpointSelectionPrioritizeLeader
with 4 t1.micro instances of AWS (3 nodes for etcd cluster and 1 node
for etcd client). Client executes this simple benchmark
(https://github.com/mitake/etcd-things/tree/master/prioritize-leader-bench),
just writes 10000 keys. When SelectionMode == EndpointSelectionRandom
(default), the benchmark needed 1 min and 32.102 sec to finish. When
SelectionMode == EndpointSelectionPrioritizeLeader, the benchmark
needed 1 min 4.760 sec.
