Create configuration for EST Profile.

Configurate the parameters of Enrollment over Secure Transport(EST) Profile. EST supports automatic enrollment of certificates with the EST Server. The certificates can be enrolled or re-enrolled automatically by
configuring an EST profile on the device. Certificate Enrollment with EST allows users to use their own PKI instead of the factory or self-signed certificates available on the Instant AP. This enables the user to
have maximum visibility and control over the management of the PKI used and address any issues related to security by themselves in a scaled environment.This feature is applicable for all devices.
