parameterise the storage class for the jenkins-mvn-local-repo pvc

[jstrachan]

then folks can opt out of standard when installing on AWS

@jstrachan I am installing fabric8 in Kubernetes cluster running in AWS through Helm. when install it for some reason jenkins-mvn-local-repo is stuck at pending

$kubectl get pvc

All the other PVC's with RWO accessmode is bounded without any issue, but "jenkins-mvn-local-repo" is requesting for RWM mode.

I am new to this fabric8 + kubernetes platform. I may be doing something wrong. Is there any configurations that i may be missing.

Any help appreciated.

thanks in advance.
