Data Sources troubleshooter generates warning that each() function is deprecated

[gbonny1982]

When Troubleshooting - Data Sources I see two error messages in the logging:

ERROR PHP DEPRECATED: The each() function is deprecated. This message will be suppressed on further calls in file: /opt/cacti/data_debug.php on line: 171
CMDPHP PHP ERROR Backtrace: (/data_debug.php[41]:form_actions(), /data_debug.php[171]:each(), CactiErrorHandler())

On Ubuntu 18.04 LTS + PHP7.2 with latest patches.

The function "foreach()" is suggested as a solution.

Hmm, I thought we'd removed all of those, this appears to have been introduced afterwards.
