- This is a new type of limit allowing to measure resource use (e.g. sent emails) per period (e.g. subscription, billing, cycle, etc)
- To enable periodical limit add following values under `hostSettings.limits`:
```
"emails": {
"maxPeriodic": 10,
"error": "Your plan supports up to {{max}} emails. Please upgrade to reenable sending emails."
}
```
and following under `hostSettings.subscription`:
```
"subscription": {
"start": "2020-04-02T15:53:55.000Z",
"interval": "month"
}
```
- Above config would allow checking if 10 emails per month starting on the 2nd of every month has been reached untill now

- This is a precursor change to tests which verify the hostSettings limits are working correctly
- Bumped limits-service version which allows for multiple calls of loadLimits on the same service instance
refs https://github.com/TryGhost/Team/issues/510
- This version bump includes follwing interface improvements of the limit-service package: passing in errors as a parameter to "loadLimits" and allowing for custom "currentCountQuery" method implementations per limit
refs https://github.com/TryGhost/Team/issues/510
- When the host config was introduced it was incorrectly introduced as host_settings instead of hostSettings
- All other Ghost config uses camelCase, so changing this now before it becomes a problem
- Note: Also removed some rogue return awaits that don't make sense. It's not possible to hit that case, but cleaning up anyway
refs: https://github.com/TryGhost/Team/issues/510
- added and wired up the new limit service, which is a lazy-loaded service
- this handles the case that there are host limits set in config, and wraps all the logic needed for detecting exceeded limits & throwing limit errors
- expects limits to be set in config under `host_settings.limits`
- supported limits are managed in the limit service, outside of core
