Allow change the deployment names

[elbandi]

We use different names for velero deployments in helm charts:

fullnameOverride: velero-helm

So this changes the deployment/pod prefix names, and we got error:

failed to ensure resources: could not get Velero deployment: velero deployment not found: deployments.apps \"velero\" not found

Can you change that this names can configured somehow?
