Request New Feature: allowing the ability to reset password during runtime for Jedis's auth

[yapei123]

Expected behavior

When Redis's password changed, without redeploy, the JedisFactory can get the new password during making a new incoming Object.

Actual behavior

JedisFactory is package protected, we couldn't extend from it to make our own customized factory.

Our proposal

1, Inside JedisPool.java, add a new constractor

public JedisPool(final GenericObjectPoolConfig poolConfig, final PooledObjectFactory<Jedis> factory) {
  	  super(poolConfig, factory);
}

2, Change JedisFactory.java to public if possible
3, Inside JedisFactory.java (Optional)

• add private final AtomicReference<String> password = new AtomicReference<String>();
• add setPassword(final String password) method

If above is approved/accepted, our application can use the new constructor to pass in JedisFactory or our own customized factory to allow reset password.
