> Param templating in shared provider config and possibly of service params 
> will be useful in order to limit the proliferation of provider config files 
> and descriptors due to params that are specific to the deployment environment.
> For instance, SSOCookieProvider can be configured to use a particular public 
> key for verifying the token signature. The public key is configured as a 
> param with the PEM encoding minus the header and footer from the PEM file.
> The ability to template this as a macro or placeholder in the provider config 
> will allow for the ability to leverage the same provider config for multiple 
> deployment environments where the value will be extracted from the gateway 
> config or runtime environment (like for the public key from the signing 
> keystore).
> This will enable multiple clusters to discover the same provider config and 
> descriptors from a single registry but still have deployment environment 
> specific values.
