[QE] fix linux e2e failure of podman

[lilyLuLiu]

Fixes: Issue #4424

@adrianriobo Could you review this pr?

[anjannath]

e2e-crc failure is about cert rotation scenario and integration-crc failure is related to the proxy scenario, both are known failures

[praveenkumar]

you really doesn't need to use platform (linux) condition here because when you unset the network-mode property it would go to default which is for linux => system-mode and for other platform user mode.

So only following should work.

err = crcCmd.UnsetConfigPropertySucceedsOrFails("network-mode", "succeeds") // unsetting property that is not set gives 0 exitcode, so this works
					if err != nil {
						fmt.Println(err)
						os.Exit(1)
					}

@praveenkumar I didn't add the platform condition at the beginning, but the check on Windows failed.

[lilyLuLiu]

The unset command will fail on both windows and mac platform.
Check in windows:

PS C:\Users\crcqe> crc config unset network-mode
Configuration property 'network-mode' does not exist
PS C:\Users\crcqe> echo $?
False

Check in mac:

lul@lul-mac hosts % crc config unset network-mode
Configuration property 'network-mode' does not exist
lul@lul-mac hosts % echo $?
1

Ah network-mode is added for linux only :(
