Redirect Binding vs Post Binding

[VivekVinushanth]

Description:
We realized that 'Include public certificate' configuration in SAML SSO Configurations is not respected by redirect binding.

Post binding : With insert public cert config, public certificate in the Authentication request
Redirect binding: With and without insert public cert config, public cert is not found in Authentication request query params and does not respect the config.

Since there are configs to include the public certificate in the IdP config and not respected when using the Redirect binding, and it is working with the POST binding, we think this is some kind of inconsistency and better if we can document this behavior.
