lvm2/test/shell/lvconvert-raid-reshape-stripes-load-reload.sh
Heinz Mauelshagen 86fa0333ff test: new raid tests
Add three new raid tests with io load and table
reloads during reshape for target 1.13.2.

Add a raid0 to raid10 conversion test.

Also add more signals to trap in lvconvert-raid-reshape-load.sh.
