haadmin should have configurable timeouts for failover commands
---------------------------------------------------------------

                 Key: HDFS-3072
                 URL: https://issues.apache.org/jira/browse/HDFS-3072
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ha
    Affects Versions: 0.24.0
            Reporter: Philip Zeyliger


The HAAdmin failover could should time out reasonably aggressively and go onto the fencing
strategies if it's dealing with a mostly dead active namenode.  Currently it uses what's probably
the default, which is to say no timeout whatsoever.

{code}
  /**
   * Return a proxy to the specified target service.
   */
  protected HAServiceProtocol getProtocol(String serviceId)
      throws IOException {
    String serviceAddr = getServiceAddr(serviceId);
    InetSocketAddress addr = NetUtils.createSocketAddr(serviceAddr);
    return (HAServiceProtocol)RPC.getProxy(
          HAServiceProtocol.class, HAServiceProtocol.versionID,
          addr, getConf());
  }
{code}
