[COMMON] Mariadb - Move liveness, readiness and startup probe values to values.yaml

Mariadb fails to come up in resource constrained environments due to the time taken to complete the db initialization.
Most of the time it is more than the startup probe initial delay. Hence the startup probe is failing and mariadb pod keeps on restarting.
This moves the liveness, readiness, and startup probe values from the template file to the `values.yaml` file for better configuration management.
