Persistent Volume Claim StorageClass

[IanBoden]

The current operator doesn't support persistent volume claim storage classes, this works fine for codeready containers which has very basic persistent volumes, but when running it on something a bit more realistic like AWS or Azure then specifying the persistent volume claim storage class is necessary. This should be a relativly simple change to make by adding the storageClass into the volumeClaimTemplate:

amlen/operator/roles/amlen/templates/statefulset.j2

Lines 86 to 93 in 6900d64

	volumeClaimTemplates:
	- metadata:
	name: data
	spec:
	accessModes: ["ReadWriteOnce"]
	resources:
	requests:
	storage: "{{_amlen_volume_size}}"

Then it will need to be added into the defauts file:
https://github.com/eclipse/amlen/blob/6900d64e8a425013f80e9246c0088549338c5d48/operator/roles/amlen/defaults/main.yml

Testing this is going to require access to a system with storage classes so using codeready containers wont be suitable. Tere are free trials and developer accounts available on different cloud providers that may be useful.
