Resources not configurable, pods can not be Guaranteed

[Tronix117]

Right now, I can't make use of this chart in our setup.
The chart should at least provide the following to be configurable :

The more important being :

• resources on every component, being able to set request/limits, and being able to have those equals is the only way to make the deployment Guaranteed, so HA. Otherwise Kubernetes may choose to remove those pods if resources are needed somewhere else

Other random stuff :

• configurable hosts, too much magic here, we should be able to set a different hostname for each component, baseDomain is not a bad idea for quick setup, but should only be used as the default one
• className for ingress should be able to be specified manualy
• PVC needs to be more customisable, the access mode is not a requirement in all setups
