Rewrite smokeping script to be an lnms command (#11585)

* Rewrite smokeping script to be an lnms command

* Add a default number of probes for smokeping

* Formatting fixes

* Refactor to simplify a couple of methods

* Fix a name collision when using more than 60 threads

* Simplify

* First pass at documentation

A few climate fixes too.

I'm a little dubious about the + LibreNMS fix - it could be included
in /etc/smokeping/config if it is really needed, but it sounds like
(looking at git blame) it's needed for if the script generates a broken
configuration file.

I'm thinking we should just not generate broken config.

* Improve testability and add some tests

* Load laravel to make translations available

* Second pass at documentation

* Fix brace

* Extend the device factory to include the type

Also adds a device group fake I created before I realised I didn't need it

* Mimic gen_smokeping.php a little more closely

* Update tests to properly verify old and new behaviour against each other

* Replace gen_smokeping with a wrapper

* Don't double whitespace

Render does this automatically.
Explicitly order by hostname too.

* Make faker less likely to generate duplicates

I tried adding a unique constraint here, but it didn't have the
intended effect.

Extending the hostname like this seems to work fine - I tried
generating 10 million hosts and got no duplicates, compared to
duplicates appearing with as few as 100 hosts without this
 change.

A true fix would be to add an 'fqdn' fake upstream.

* Make the tests more robust

* Assorted bug fixes

* Style corrections

* Handle 'generic' devices

* Fix an issue that came up during rebase
