[Bug] Adding a metric with a slash(/) in the ID causes 404 errors when trying to edit the metric

[cullorblind]

Just ran into this one. I didn't see any other obviously related issues.

• What SnmpCollector version are you using? 0.13.1 commit d645bf2
• What OS are you running snmpcollector on? Debian 11
• What did you do? One of our techs added a metric with a slash(/) in the name, and was unable to edit that metric from the gui.
  eg. AVIAT-RF-MIB::aviatRfFreqTx-Carrier1/1
• What was the expected result? Metrics shouldn't 404 when loading.
• What happened instead? Received red 404 page not found alert box when clicking on metric edit button.

I was able to fix this instance by using sqlite3 to rename the metric IDs.

• eg.
  sqlite> update snmp_metric_cfg set id="AVIAT-RF-MIB::aviatRfFreqTx-Carrier1-1" where id="AVIAT-RF-MIB::aviatRfFreqTx-Carrier1/1"
  sqlite> update measurement_field_cfg set id_metric_cfg="AVIAT-RF-MIB::aviatRfFreqTx-Carrier1-1" where id_metric_cfg="AVIAT-RF-MIB::aviatRfFreqTx-Carrier1/1";
