[#24029] Update the callhome diagnostics not to send gflags details.

Summary: Currently, collecting gflags information is redundant data between yugabyted and YBDB callhome. It was decided to not send gflags information from yugabyted, instead correlated the data using cluster_uuid, node_uuid, server_type for fetching the gflags details.

Test Plan: manual test
