Description of problem:

qpid c++ client API allows to specify connection options using simple string format:
  Connection (const std::string &url, const std::string &options)
     Creates a connection using an option string of the form
     {name:value,name2:value2...}, see above for options supported. 

This way of connection option specification is very convenient and should be supported across all other languages. (specifically python API does not support it)



Version-Release number of selected component (if applicable):
2.1.2 qpid-0.14

How reproducible:
N/A

Steps to Reproduce:
1. see documantation on qpid::messaging::Connection
2. see documentation on qpid.messaging.Connection (pydoc qpid.messaging.Connection)
  
Actual results:
String-like connection options available in c++ client is not in other client libs.

Expected results:
String-like connection options available in c++ client should be available in other client libs.
