Feature/initial implementation

[sitepark-veltrup]

Initial implementation of the atoolo search.

[sitepark-schaeper]

looks good so far, just a couple small things remaining

[sitepark-veltrup]

The following issues apply to most Commands:

• There are a couple of phpcs:ignore comments scattered which I believe we don't need.
• The resource-dir and path arguments beeing hard to differentiate.
• The Commands that use a builder-pattern should check if all (required) properties have been set when build() is invoked.

obsolete

What about this comment from earlier on?:

For the big constructors (especially) it's probably usefull to use named arguments. Compare the following:

        $this->status = new IndexerStatus(
            IndexerStatusState::RUNNING,
            new DateTime(),
            null,
            $total,
            0,
            0,
            new DateTime(),
            0,
            0
        );

        $this->status = new IndexerStatus(
            state: IndexerStatusState::RUNNING,
            startTime: new DateTime(),
            endTime: null,
            total: $total,
            processed: 0,
            skipped: 0,
            lastUpdate: new DateTime(),
            updated: 0,
            errors: 0
        );

found a couple more instances where named arguments are probably worth using
