E2e: Enable bring your own OpenStack

[lentzi90]

/kind feature

Describe the solution you'd like

Our e2e tests currently require OpenStack admin credentials. My understanding is that it is only required for creating the volume type here:

cluster-api-provider-openstack/test/e2e/suites/e2e/e2e_test.go

Lines 861 to 880 in c73d55d

	func createTestVolumeType(e2eCtx *shared.E2EContext) {
	providerClient, clientOpts, _, err := shared.GetAdminProviderClient(e2eCtx)
	Expect(err).NotTo(HaveOccurred())
	volumeClient, err := openstack.NewBlockStorageV3(providerClient, gophercloud.EndpointOpts{Region: clientOpts.RegionName})
	Expect(err).NotTo(HaveOccurred())
	shared.Logf("Creating test volume type")
	_, err = volumetypes.Create(volumeClient, &volumetypes.CreateOpts{
	Name: e2eCtx.E2EConfig.GetVariable(shared.OpenStackVolumeTypeAlt),
	Description: "Test volume type",
	IsPublic: pointer.Bool(true),
	ExtraSpecs: map[string]string{},
	}).Extract()
	if capoerrors.IsConflict(err) {
	shared.Logf("Volume type already exists. This may happen in development environments, but it is not expected in CI.")
	return
	}
	Expect(err).NotTo(HaveOccurred())
	}

If possible, I would like to change this so that the volume type can be pre-existing and configured like the other OpenStack variables. This would make it possible to run the e2e tests without OpenStack admin credentials, e.g. against a public OpenStack cloud.

Anything else you would like to add:
This should be a pretty good first issue.
