$GLOBAL_OPTS runlabel is not implemented

[edsantiago]

$GLOBAL_OPTS was added in #2905. Only one month later it got broken, and the test was "temporarily" disabled in #3328:

Completely disable global options test
We need to cut a release. We can investigate further next week.

Obviously nobody has used this feature since June 2019. It might not be important enough to reimplement. If so, it should be removed from the code and documentation.

Possible reproducer:

$ printf "FROM alpine\nLABEL RUN echo \$GLOBAL_OPTS\n" | bin/podman --log-level error --tmpdir /var/tmp build -t foo:bar -
...
$ bin/podman --log-level error container runlabel RUN foo:bar
[expect: something with `--log-level`. Actual output: nil]

(I may have the number of backslashes wrong in the line above. It's impossible to know, because the code doesn't trigger no matter how many backslashes I add).

GLOBAL_OPTS only works with podman runlabel not with podman build?

I'll take a look. As always, thanks @edsantiago for the great reports.

If you find the problem, there's already a test you can un-skip:

podman/test/e2e/runlabel_test.go

Lines 107 to 109 in 9af07fd

	It("podman container runlabel global options", func() {
	fmt.Printf("FIXME: for lint. Remove when you fix this test: %s", GlobalDockerfile)
	Skip("FIXME: $GLOBAL_OPTS does not work at all, #12436")

Thanks!
