I'm estimating this to be a fairly simple PR, so (according to https://github.com/prometheus/mysqld_exporter/blob/main/CONTRIBUTING.md): Thanks :) |

This
sysschema is another (mariadb-specific) "system" schema, introduced in MariaDB 10.6 (2021), cf: MariaDB's docEDIT: MySQL seems to be introducing also a
sysschema in MySQL 8.4 (2024), cf: MySQL's docAnd it's not useful to collect metrics for this schema (and it's even counter-productive, cf the cost of storing the metrics afterwards).
So, let's just remove this schema, just like it's already performed for the other "system" schemas (ex:
performance_schema) today to be consistent with all "system" schemas.Note: it's my first PR here, so I'm not sure about the CI/tests, please forgive any mistake & tell me 🙏
