Ability to specify SSL parameters for python-clients used

Heat uses client libraries for of OpenStack services. Those services may be configured to use HTTPS instead of HTTP. So to access them you need to pass SSL-related parameters to client constructor. Currently this is not possible with Heat. The level of SSL support varies from client to client but there is a common set of options that can be possibly be for any given service. I want to have solution that would allow configure each client independently. I also want to have ability to define a shared configuration for all clients so that I wouldn't have to repeat all the settings for each client. Shared config section would act as a fallback if client-specific config section is not found (or setting is missing)
