Add multiple storefront support

[Jon5eve]

Please describe the feature you would like to see implemented.

It would be nice to access all storefronts from shopmon. Especially in a headless setup, a storefront on the admin url is not helpful. Support for the Pagespeed feature would be the cherry on the top.

I am not sure if it would be better to maintain each storefront url in shopmon or to get all saleschannel urls from shopware.

I don't understand the need for multiple storefronts? Shopmon is to monitor the system itself and not the storefronts. Can you describe your use case?
