MINOR: server/event_hdl: add proxy_uuid to event_hdl_cb_data_server

Expose proxy_uuid variable in event_hdl_cb_data_server struct to
overcome proxy_name fixed length limitation.

proxy_uuid may be used by the handler to perform proxy lookups.
This should be preferred over lookups relying proxy_name.
(proxy_name is suitable for printing / logging purposes but not for
ID lookups since it has a maximum fixed length)
