[e2e] Fix Panic in PersistentVolumes:vsphere

cluster/gce and test/: update etcd:3.2.24-0 image to etcd:3.2.24-1

Bootstrap initializes the necessary vSphere objects before the tests are
run. A call to Bootstrap was missing in persistent_volumes-vsphere.go's
BeforeEach. This results in Panic while running e2e tests for 'vsphere'
provider with a stack trace like this:

  	/usr/local/go/src/runtime/panic.go:502 +0x229
  github.com/docker/kube-e2e-image/vendor/k8s.io/kubernetes/test/e2e/storage/vsphere.glob..func1.1()

  github.com/docker/kube-e2e-image/vendor/github.com/onsi/ginkgo/internal/leafnodes.(*runner).runSync(0xc4217c9b60,
0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, ...)
  	/go/src/github.com/docker/kube-e2e-image/e2e_test.go:88 +0x2c8
  testing.tRunner(0xc4206e01e0, 0x4212900)

  created by testing.(*T).Run
  	/usr/local/go/src/testing/testing.go:824 +0x2e0

This change fixes the Panic by calling Bootstrap.

Testing:
After this change, tests with FOCUS set to "PersistentVolumes:vsphere"
 dont Panic. They pass as expected.

Also re-format the error message because the version is not validated
per maximum basis, but rather based on existing validation.
