no longer hard code storageClass and don't assume RWX

[NerdyShawn]

Fixes issue # 8651

Changes in this pull request:

• Remove hardcoded value of storageClass for the db chart inside the stack chart
• Remove ReadWriteMany accessMode hardcode as well, as this will also depend on if the storageClass used supports it

Alright check out the lint errors, and make sure it works before AND after your changes, also if you do have nfs available.

Ok so I've validated the values on a civo cluster and a local on prem raspberry pi cluster with different storageClasses. Both pvc's are now installing ok for me with their respective storageClasses.

The issue I'm running into at both sites is something about an application key missing, though I think that was a separate issue I was seeing before these changes anyway.

Updated version.

I assume that's because of the password field used in the env config in the chart? I didn't find any k8s secret deployed to reference for database creds perhaps causing the app pod to never go healthy maybe? Sorry not trying to mix the two issues, but I haven't used the app yet was mainly trying to give it a spin via helm first.
