[Stratos-dev] Update on the platform sample.

Hi Shariq,

To secure the FinancialConnectorService, we placed a policy reference in the
WSDL file and bundled it with the service with the useOriginalWSDL param set
to 'true' in services.xml file. But in this case, this policy file should be
stored in each tenant's gov. registry and it should be referred from the
FinancialConnectorService.

Similarly the client(in this case, the corresponding EP) should be referring
to the correct policy.

We will have to figure out the proper way of handling this scenario.

Thanks,
Thilina
