From 90b6b709e9f4002376b656b155d00d85382f1828 Mon Sep 17 00:00:00 2001
From: Pavel Moravec <pmoravec@redhat.com>
Date: Mon, 29 Mar 2021 16:23:01 +0200
Subject: [PATCH] [report] add --cmd-timeout option
Add --cmd-timeout option to configure command timeout. Plugin-specific
option of the same name (i.e. -k logs.cmd-timeout=60) can control the
timeout per plugin.
Option defaults and global/plugin-specific option preference follows the
--plugin-timeout rules.
Resolves: #2466
