Part 1:

When default StorageClass is configured to have volumeBindingMode set to WaitForFirstConsumer, workspaces do not start. I guess that's because che is waiting for PVC to be in "Bound" state before creating workspace (or mkdir) pod. But this is not happening with this volumeBindingMode and the PVC is stuck in "Pending" state with message "waiting for first consumer to be created before binding" until the workspace startup fails.

Reproduction Steps
Create default StorageClass with WaitForFirstConsumer volumeBindingMode (more info here)
Try to start workspace
Workspace startup fails with message:

Error: Failed to run the workspace: "Waiting for persistent volume claim 'claim-che-workspace' reached timeout"

Part 2:

Do not wait for PV state bound if we got a message "waiting for the first consumer to be created before binding"
