Provide a way to change API nb_ data period

[EthraZa]

Right now, all the nb_ data on the API are the sum of the last 14 days and are used to show stats on the UI (with exception of nb_aliases that is the sum of all aliases under that user).
If the nb_ data where telling about the current month, for example, it would be more easy to me to imagine uses for it.

• nb_ feature request:
  I would like to suggest 2 scenario options to enhance this data so it get useful for more people.

I'm guessing the scenario 1 (custom period) would be the easiest to implement maintaining backward compatibility.
But, scenarios 2.0 and 2.1 are for if, for some reason, to offer a custom period is out of possibility.

1. Custom period:

GET /api/v2/aliases? nb_days=30  // If omitted, default is 14 

The resulting JSON would keep the same as the current one.

• The server implementation could have a limit cap for this one, or you could just set a generous enough hardcoded limit cap like 90 days.

---

2. Fixed periods:

Monthly data:

"month_current": {
    "nb_block": 0,
    "nb_forward": 1,
    "nb_reply": 0
},
"month_last": {
    "nb_block": 1,
    "nb_forward": 2,
    "nb_reply": 1
}

Alternative...

Monthly / Weekly data:

"month_current": {
    "nb_block": {
        "week_1": 0,
        "week_2": 2,
        "week_3": 4,
        "week_4": 1
    },
    "nb_forward": {..},
    "nb_reply": {..}
},
"month_last": {...}

Hey the 14 days is actually a set limit in SimpleLogin: all logs are deleted after 14 days. As these logs aren't linked to users, they are deleted in batch.

I assume you are talking about a server option we can tweek in the self hosted version. I use the SL.io service and I have no option in the Settings page, at least, none I can spot.
If this option already exists, would be cool if I can change it in the Settings page but, be able to change it at call time to the API would be superb. I'm sayning that because, like today, November 16, if I could see the statistics for the last 16 days, would be more useful then see the one for the last 14 days that skeeps days 1 and 2 of Novemeber that could have important info to take into account.

So, if I'm not being a total noob by missing an option that is already there, is it possible to add this to the Settings page of the UI?
And about the API, if the options already exists in SL, I'm guessing the API param exists too, it's only undocumented, or no?

The 14 days data deletion is actually a hardcoded config on SL.io. On a self hosted instance, there's no automatic data deletion though.

As this number is hardcoded, it isn't configurable. Its use is here
