Fix client IP logging in Keystone API VirtualHost

The VirtualHost CustomLog directive was overriding the server-level
dual-log setup, causing all requests to be logged with the OpenShift
router IP instead of the real client IP from X-Forwarded-For.

Add SetEnvIf and dual CustomLog lines inside the VirtualHost block
to match the nova-operator pattern.
