feat: API endpoint for service count and updates available

[PedroBuffon]

Feature request to add an API point for Updates count available and APP count. I`m currently doing a Heimdall Dashboard APP for Argus and as there is no api endpoint for Update counter and APP counter i would need to convert the /metrics to json and program from there.

Hi,
I don't personally use Heimdall, but I have heard it mentioned a lot and it's nice to see an interest in adding Argus to it.
I could add something like /api/v1/counts that gives

{
  "service_count": 5,
  "updates_available": 3,
  "updates_skipped": 1
}

Would that work for you?

(Haven't got round to adding Auth yet so will just be a simple GET request until I get to that)

[PedroBuffon]

So what i was thinking was something like what i did with when i did the Enhanced version of gotify:

But changing the values for the ones you put on the json you mentioned

{
  "service_count": 5,
  "updates_available": 3,
  "updates_skipped": 1
}

and having only one endpoint to get those information make everything easier, only one request and that`s it. If that picks your interest, the link for the branch is https://github.com/PedroBuffon/Heimdall-Apps/tree/EnhancedArgus

I've just added this with 8364209 and will do a release shortly.
/api/v1/counts
gives

{
  "service_count": 5,
  "updates_available": 3,
  "updates_skipped": 1
}

Skipped updates still show as available. So if you had 1 update available but unskipped, it would give

  "updates_available": 1,
  "updates_skipped": 0

and if you then skip that update, it would update to

  "updates_available": 1,
  "updates_skipped": 1

Tested on Homepage and works amazing

Looks very nice, thanks for adding this @PedroBuffon :)

I'll update the Heimdall app code when I get home.
