[OADP] Velero has wrong timezone and we are unable to change it

Validation Steps

Set env TZ like so to desired timezone.

apiVersion: oadp.openshift.io/v1alpha1
kind: DataProtectionApplication
metadata:
  name: dpa-sample
  namespace: openshift-adp
spec:
  configuration:
    velero:
      podConfig:
        env:
          - name: TZ
            value: America/New_York

Notice in velero pod logs that timestamps now include offsets from UTC seen here `-04:00`

time="2023-03-14T10:57:24-04:00" level=info msg="Starting Velero server v1.9.5-OADP (-)" logSource="/remote-source/velero/app/pkg/cmd/server/server.go:183"

Create a schedule
Notice in velero pod logs that backup generated name has the exact same hour/minute numbers
Seen below 2023-03-14T11:00:04 matches up with 20230314110004

time="2023-03-14T11:00:04-04:00" level=info msg="No Schedule.template.metadata.labels set - using Schedule.labels for backup object" backup=openshift-adp/schedule-20230314110004 labels="map[]"

Description of problem:

In this case: TimeZone

We could ensure the oadp-controller also has the TZ config or we could better handle any env config available to velero container running in docker.

I wonder if we could append it to the velero container here: https://github.com/openshift/oadp-operator/blob/master/controllers/velero.go#L486 (edited) 
 

maybe could do something like add the value to the OADP api in the velero config (what Dylan pointed out). Write a func to check whether or not that value is set. If so, append that env var with the value in DPA to the velero container
 
Notes from Dylan:
https://github.com/openshift/oadp-operator/blob/master/api/v1alpha1/oadp_types.go#L66
 
 
basically just add it here
 

Which version we'll fix this in is TBD.
