Subject: [PATCH] Allow clearing all records on an internal data group

The Records field on dataGroupDTO was tagged `json:"records,omitempty"`, so a PUT
with an empty record set sent no `records` field at all and BigIP kept the existing
entries. Drop omitempty so callers can clear records by passing an empty slice
(which now serializes as `"records": []`).

Mirrors the vendor patch in F5Networks/terraform-provider-bigip#1165.
