Summary

Fixes two issues with non-SLA alerting for all AppCat services:

  1. MariaDB container name - MemoryCritical alert was querying wrong container (mariadb instead of mariadb-galera)
  2. Regex capture groups - label_replace() patterns missing parentheses, breaking $1 substitution in alert labels
  3. Alert flapping - PersistentVolumeFillingUp firing repeatedly due to the duration being 1 minute. This is increased to 15 minutes

Component PR: vshn/component-appcat#1070

This fixes the wrong container name being used for the user alerting of
mariadb. This also fixes an issue with inproper parentheses in the regex
capture groups.

This increases the interval of the pvFillUp alert from 1 minute to 15
minutes to prevent repeated alerts due to flapping.
