feat(health): Implement k8s.mariadb.com CRD health checks

[sennerholm]

Health checks for k8s.mariadb.com (https://github.com/mariadb-operator/mariadb-operator) objects, the new name of the mariadb.mmontes.io objects. The main MariaDB healtcheck is also the same.

I doesn't have added "Healthy" testdata and some none-healthy cases, and is asking the users in slack for more samples on "Non Healthy" states that I will add in the future if I get some.
