Docs: Feedback for REST API

[pmcgleenon]

Hi, I have some feedback about this page

Hazelcast provides a REST API that allows you to access your data structures and cluster using HTTP/HTTPS protocols.

The REST API allows you to manage the configuration for data structures and configure and manage the cluster.
To avoid any confusion, it's worth pointing out that the REST API is a control-plane API for the cluster which is useful for configuration and operational purposes. It does not provide direct access to any data stored in distributed data structures.
