Add -U / --show-url option to the ITL http CheckCommand

[0uLoL]

Description

The check_http plugin provided by the nagios-plugins/nagios-plugins project supports the following option:

-U, --show-url
    Show the checked URL in the plugin output

This option is currently not exposed by the Icinga Template Library http CheckCommand.

The option is not present in the ITL definition included with Icinga 2.15.4. It is also missing in Icinga 2.16.2 and in the current master branch.

Use case

When several URLs are monitored, the default plugin output does not necessarily make it clear which URL was checked.

Environment

• Icinga 2 version currently in use: 2.15.4-1
• Also checked against the ITL definitions from Icinga 2.16.2 and the current master branch
• Check plugin: check_http from nagios-plugins/nagios-plugins

Thanks for creating this issue.

Please note that there are slight differences between the Monitoring Plugins and the Nagios Plugins. This flag is one of those available in the Nagios Plugins¹, but not in the Monitoring Plugins². While this does not hinder an implementation, this should be kept in mind and documented accordingly.

You are very welcome to create a PR with a patch.
