runtime-rs: Support share-rw=true when hotplug block device within qemu

Browse Source 
Support for the share-rw=true parameter has been added. While this
parameter is essential for maintaining data consistency across multiple
QEMU instances sharing a backend disk image, its implementation also
serves to standardize parameters with the block device hotplug
functionality in kata-runtime/qemu.
