[BACKPORT 2.20][#24029] Update the callhome diagnostics not to send g…

…flags 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.
