Epic Goal

When provisioning a new PV fails, for example due to lack of storage, the admin currently sees only a "ScheduleFailed" event with "not enough storage" from the kube scheduler.

It can be hard to debug and understand whats going on behind the scenes, esp. when "spare-gb" setting is used. Looking at the VG the admin sees space available, still the provision fails (correctly).

The goal of this epic to provide more detailed error messages to the admin. A "natural" place to look for is the "status" field of the PVC. Can we have a Error message like

"Can't create PV because not enough storage. Node X has Y amount of storage free (Z Gb blocked by spare capacity) [repeat for all nodes]"

Other error messages should also show up there (e.g. if PV creation fails due to invalid pvcreate options, errors from LVM, LVMD etc.)

Why is this important?
