Multiple changes for Bug #543064

Browse Source 
1. Provided SetATSHostList() API for changing the ATS address dynamically
2. Not using CASA enabled server as ATS. ATS address has to be explicitly set
   in client.conf or through SetATSHostList()
3. Not normalizing CASA enabled server's host name while obtaining CASA tokens.
   Callers of ObtainAuthTokenEx() have to pass normalized name as argument
