virsh: Create macro for common "persistent" option
virsh: Create macro for common "persistent" option

Rather than continually cut-n-paste the strings into each command,
create a common macro to be used generically.  Note that not all
'{.name = "persistent",' entries are replaced, just those that have the
common .help string of "make live change persistent".

Non replaced instances are unique to the command.
