improve error handling in e2e helpers

**What this PR does / why we need it**:
Changes most of the volume related helper funcs to return error rather than calling `Expect`. This is a better programming practice, is consistent with Go and Kubernetes, and allows helper funcs that create multiple resources to perform cleanup.
