Identity Broker for Frontier chris21 - ability to use SSL with certificate that doesn't match endpoint address

CloudBroker requires the following:

• SSL on all communication

IDBCHRS will fail if the end-point address (a public DNS entry) is different to the certificate supplied by the IIS end-point, something that is entirely likely to happen if a customer cannot use their NAT to set up SSL and terminate at that address. For example:

IDBCHRS is set to connect to unify-demo-idbchrslite-1-chrs.cloudapp.net, however the AD certificate is issued by the domain CA which makes the certificate idbpc21-chrs.demo.unifysolutions.net.

The chris21 connector should permit the certificate to be determined by a name in the our configuration. The certificate must still be valid against the local machine certificate store.
