HDFS-16718. Improve Code with Lambda in org.apache.hadoop.hdfs.server.datanode packages

[ZanderXu]

Description of PR

Improve Code with Lambda in org.apahce.hadoop.hdfs.server.datanode packages.

For example:
Current logic:

synchronized void startAll() throws IOException {
  try {
    UserGroupInformation.getLoginUser().doAs(
        new PrivilegedExceptionAction<Object>() {
          @Override
          public Object run() throws Exception {
            for (BPOfferService bpos : offerServices) {
              bpos.start();
            }
            return null;
          }
        });
  } catch (InterruptedException ex) {
    IOException ioe = new IOException();
    ioe.initCause(ex.getCause());
    throw ioe;
  }
}

Improved Code with Lambda:

synchronized void startAll() throws IOException {
  try {
    UserGroupInformation.getLoginUser().doAs(
        (PrivilegedExceptionAction<Object>) () -> {
          for (BPOfferService bpos : offerServices) {
            bpos.start();
          }
          return null;
        });
  } catch (InterruptedException ex) {
    IOException ioe = new IOException();
    ioe.initCause(ex.getCause());
    throw ioe;
  }
}
