Recreate indexes of upgradeable packages and plugins.
As an alternative every OMV plugin should execute a trigger during install/uninstall, thus the index creation must not done by the RPC. This will only work for plugins, the upgradeable packahe index can only be rebuild via RPC. Sadly APT/DPKG does not support hooks for clean/install/remove :-(
