The DNSSEC refresh cron job still uses the Perl version

[zrhoffman]

This Improvement request (usability, performance, tech debt, etc.) affects these Traffic Control components:

• Traffic Ops

Current behavior:

The Traffic Ops DNSSEC refresh cron job still uses the Perl implementation:

trafficcontrol/traffic_ops/etc/cron.d/trafops_dnssec_refresh

Line 18 in a971b6c

*/5 * * * * trafops export PERL5LIB=/opt/traffic_ops/app/local/lib/perl5:/opt/traffic_ops/app/lib; /opt/traffic_ops/app/bin/checks/ToDnssecRefresh.pl -c '{ "base_url": "https://127.0.0.1" }' -l 1 > /var/log/traffic_ops/trafops_dnssec_refresh.log 2>&1

New behavior:

The cron job should use the Go implementation (/traffic_ops/app/bin/checks/DnssecRefresh/ToDnssecRefresh.go).
