pip_requires for specific plugins

[Sumit Naiksatam]

Currently all the package dependencies for the Quantum framework are captured in quantum/tools/pip_requires. Individual plugins might have additional dependencies. It will be helpful to have some way of specifying those from with the plugin.

[Tyler Smith (tylesmit)]

Fix pushed to Gerrit. Plugins can put a pip-requires file in plugins/PLUGIN/pip-requires. When tools/install_venv is installing dependencies it will find all pip-requires and install them all.

Whats nccclient?

ncclient is a library required by the Cisco plugin in order to communicate with the Cisco Nexus device.
