Release 7.4.1: Removed JCS related options from oxinstaller

[Guest]

Since 7.0.1 JCS cache invalidation is performed by our own invalidation mechanism. Currently the oxinstaller script enables UDP discovery for JCS. Internally these settings are already ignored due to our own invalidation mechanism. Thus enabling the mentioned settings makes no sense anymore.

These options have been removed from oxinstaller:
--cache-udp-disc-addr
--cache-udp-disc-port
--admin-cache-port
