Hitoshi Mitake f8a290e7ca *: support jwt token in v3 auth API
This commit adds jwt token support in v3 auth API.

Remaining major ToDos:
- Currently token type isn't hidden from etcdserver. In the near
  future the information should be completely invisible from
  etcdserver package.
- Configurable expiration of token. Currently tokens can be valid
  until keys are changed.

How to use:
1. generate keys for signing and verfying jwt tokens:
 $ openssl genrsa -out app.rsa 1024
 $ openssl rsa -in app.rsa -pubout > app.rsa.pub
2.  add command line options to etcd like below:
--auth-token-type jwt \
--auth-jwt-pub-key app.rsa.pub --auth-jwt-priv-key app.rsa \
--auth-jwt-sign-method RS512
3. launch etcd cluster

Below is a performance comparison of serializable read w/ and w/o jwt
token. Every (3) etcd node is executed on a single machine. Signing
method is RS512 and key length is 1024 bit. As the results show, jwt
based token introduces a performance overhead but it would be
acceptable for a case that requires authentication.
