Subject: [PATCH] Reraise exceptions to preserve stack traces

Otherwise, you can hit errors with tracebacks like

   Traceback (most recent call last):
     ...
     File ".../kmip/pie/client.py", line 1573, in __enter__
       self.open()
     File ".../kmip/pie/client.py", line 135, in open
       raise e
   IOError: [Errno 2] No such file or directory

... which isn't terribly useful; it doesn't give you any information
about *what* file wasn't found. By using a bare `raise`, you preserve
the rest of the stack and get

   Traceback (most recent call last):
     ...
     File ".../kmip/pie/client.py", line 1573, in __enter__
       self.open()
     File ".../kmip/pie/client.py", line 131, in open
       self.proxy.open()
     File ".../kmip/services/kmip_client.py", line 221, in open
       self._create_socket(sock)
     File ".../kmip/services/kmip_client.py", line 246, in _create_socket
       suppress_ragged_eofs=self.suppress_ragged_eofs)
     File ".../eventlet/green/ssl.py", line 379, in wrap_socket
       return GreenSSLSocket(sock, *a, **kw)
     File ".../eventlet/green/ssl.py", line 68, in __init__
       ca_certs, do_handshake_on_connect and six.PY2, *args, **kw)
     File ".../ssl.py", line 558, in __init__
       self._context.load_verify_locations(ca_certs)
   IOError: [Errno 2] No such file or directory

... which makes it clear that it was a problem with the CA certificate
bundle.
