Horizon: Exclude certain jobs from Completed Jobs list

[hailwood]

Right now Horizon displays all jobs that have completed in the Completed Jobs list.
This is great, unless you've got jobs running that you don't really care about -

For example we use OhDearApp so if the job fails we'll know about it from OhDearApp notifying us.
The issue we run into is that it fires one job per scheduled task per execution - and this is drowning out the less often jobs we do care about.

It would be great if either in the horizon config we could have a way to say 'hide these jobs'

'hide_completed_jobs' => [
    PingOhDearJob::class,
],

Or a closure based approach like (complete pseudocode)

Horizon::filterJob(function(Job $job) {
   return $job->className !== PingOhDearJob::class || !$job->isComplete;
});

I like the idea here. Maybe the following config?

'jobs' => [
    'exclude' => [
        PingOhDearJob::class,
    ],
],

I'll ping @taylorotwell to see if we can accept a PR for this.

I'm fine with this if someone wants to make a PR. 👍
