[functional][u][sporadic][medium] test fails in snapper_cleanup because of "config is in use" - should we wait in subsequent snapper calls for the previous to finish?

Description

Observation

openQA test in scenario opensuse-Tumbleweed-DVD-x86_64-extra_tests_filesystem@64bit fails in
snapper_cleanup
with "config is in use". So it seems that snapper itself is still busy from the previous call and we did not wait long enough before calling the next command.

Reproducible

Fails since (at least) Build 20180424

Expected result

Last good: 20180423 (or more recent)

Suggestion

I think we just need to wait until we can call snapper again, e.g. try again after some waiting time until it finishes, e.g.

my $failed;
my $max_retries = 7;
for (1 .. $max_retries) {
    $failed = script_run 'snapper cleanup …';
    last unless $failed;
    report_info "Retry $_/$max_retries", 'Retrying …';
    sleep 1;
}
die "snapper cleanup did not finish successfully even after $max_retries tries" if $failed;

did see this in https://openqa.opensuse.org/tests/748992#step/snapper_cleanup/140 which is going from most recent https://openqa.opensuse.org/tests/763579 over the history 1/50 so valid still

http://e13.suse.de/tests/10947#next_previous shows no issue at all for 100 test runs.

on 3o we don't see this issue anymore:

https://openqa.opensuse.org/tests/latest?flavor=DVD&arch=x86_64&version=Tumbleweed&test=extra_tests_filesystem&distri=opensuse&machine=64bit#next_previous

I don't think cleanup created snapshots is a problem: assert_script_run("snapper cleanup number", 300); # cleanup created snapshots
300 is enough.
