Support for ipv6

[VenkateshRamalingam]

Two different issues needs to be addressed, listed below

1. At the moment MCP2 has support for ipv6 so using public ip for all the http request does not work, please refer the suggested fix by @tonybaloney
   https://github.com/DimensionDataCBUSydney/plumbery/commit/3937832e784ad8a4ce6b6216de36209791b60227
2. Even if we add support for the ipv6, python does not handle the ipv6 in the url and will throw the url parser error as below

InvalidURL
Failed to parse: 2402:9900:211:1223:3a19:3ea0:3dd1:533a

To reproduce this issue please follw the steps below,

• Install Python 3.5.2 https://www.python.org/downloads/
• Install the plumbery development environment https://docs.mcp-services.net/display/PLUM/Getting+started
• Apply the above code fix in the plumbery code.
• Deploy the below fitting file
