Remove support for "lvm_share_export_ip"
The LVM driver accepts a "lvm_share_export_ips" option instead of "lvm_share_export_ip" since the Pike release [1]. Let's drop support for this option and cleanup compatibility code. [1] Ib3594aa5d7751c829820fce830d87f6ceea6b049 Change-Id: Ifdeb470438c204cc6cc370517833cb2cab5b7822
