Description

Previously we removed all the third-party python modules from HAWQ code for License incompatible concerns.

After that, users need to install many python modules by themselves. But in some environment, use pip to install python modules are painful.

As my check, only 'paramiko' is not compatible with Apache HAWQ License. So I suggest we add the python modules back into our code. For 'paramiko' we can find another python module to replace it. Once we finished this, user won't need to install any python modules.

Attached the list of the python module license:

paramiko LGPL
figleaf BSD
pg8000 BSD
pygresql Python
simplejson MIT
pyyaml MIT
lockfile OSI Approved :: MIT License
