What's new

• Fix inconsistent cache key format in _ConnectionManager between getConnection() and _connect(),
  which caused _transportsMap.remove() to fail silently during idle timeout cleanup and led to memory leaks.
• Add handshakeTimeout (defaults to 15 seconds) to the ConnectionManager to prevent long waiting
  if there's something wrong with the handshake procedure.
• Provides httpVersion in Response.extra.
