Subject: [PATCH 1/6] Fix spurious recreate of external volumes with
 trailing-slash storage_location

The UC API strips trailing slashes from storage_location on create, causing
the direct engine to detect drift on every subsequent plan and trigger a
full delete+create cycle.

Fix: add OverrideChangeDesc to ResourceVolume that treats storage_location
values differing only by trailing slashes as equivalent (alias), matching
the Terraform provider's suppressLocationDiff behavior.

Also update the testserver to accept storage_location on EXTERNAL volumes
and strip the trailing slash, mirroring UC API behavior so the bug and fix
are reproducible locally. Add an invariant no_drift test for external volumes.
