                 Key: HBASE-24570

In the ConnectionImplementation construction method, if getRegistry throws exception， registry will be null，and then close will throw NPE
{code:java}
try {
  this.registry = AsyncRegistryFactory.getRegistry(conf);
  ...
} catch (Throwable e) {
  // avoid leaks: registry, rpcClient, ...
  LOG.debug("connection construction failed", e);
  close();
  throw e;
}
{code}
