Test cases against nodeset error handling

The main purpose of these test cases is verify the changes made by pull request #4037 [1].

[1] https://github.com/xcat2/xcat-core/pull/4037

A handful of bogus xCAT node definitions will be created, and xCAT command nodeset will be run against these bogus node definitions. After the command was run, check the outputs and exit codes to see if the error handling worked fine.

Scenario 1

One node has no MAC address available in its node definition. Run nodeset <noderange> osimage=<osimage>

Scenario 2

One node has no arch attribute set in its node definition. Run the following commands

nodeset <noderange> shell
nodeset <noderange> runcmd=bmcsetup
nodeset <noderange> runimage=/non/existant/image
nodeset <noderange> standby

nodeset <noderange> osimage
nodeset <noderange> osimage=an-osimage
nodeset <noderange> osimage=non-existant-osimage

Scenario 3

One node has serialport set in its node definition but serialspeed is not set. Run the following commands

nodeset <noderange> shell
nodeset <noderange> runcmd=bmcsetup
nodeset <noderange> runimage=/non/existant/image
nodeset <noderange> standby

nodeset <noderange> osimage
nodeset <noderange> osimage=an-osimage
nodeset <noderange> osimage=non-existant-osimage

Scenario 1, 2 and 3 should be run against nodes with netboot=petitboot, netboot=xnba and netboot=grub2
