Ability to specify wait time

[emmetog]

Sometimes the copy-twice-name strategy needs more time to complete because of dynamically provisioned volumes, 60 seconds is often just at the limit of what it needs. Would be nice to be able to specify a bigger wait time like this for example:

korb data-postgresql-0 --source-namespace default --new-pvc-storage-class new-csi-ratain --strategy copy-twice-name --timeout 360

Here's a timeout on my setup:

...
DEBU[0060] Pod not in correct state yet                  component=mover-job phase=Pending
DEBU[0060] Pod not in correct state yet                  component=mover-job phase=Pending
WARN[0060] failed to wait for pod to be running          component=mover-job error="timed out waiting for the condition"
WARN[0060] Failed to move data                           component=strategy error="pod not in correct state" strategy=copy-twice-name
INFO[0060] Cleaning up...                                component=strategy strategy=copy-twice-name
