* Add ondiscover support for chain table
* For ondiscover, run nextdestiny after the current operation is done
* Don't set OpenPower server boot from network if boot
- zvmdiscovery plugin will not handle findme
- not change request if no temp discovered bmc nodes, to avoid the confusing error message
- add more logs, and ignore the `ipmitool sol info` error output
RH7/Centos7 and recent versions of fedora relocate `/*bin/*` into `/usr/*bin/`. This causes
conflicts for upgrades against xCAT-genesis-scripts-* packages which expect the `/bin` a to be
a directory while `xCAT-genesis-base-*` packages provide a link. Relocating all files into `/usr`
fixes that conflict and allows a clean upgrade from all old versions.
