We're rolling out new rules around the node assert library, the first of which is enforcing the use of assert/strict. This means we don't need to use the strict version of methods, as the standard version will work that way by default.
This caught some gotchas in our existing usage of assert where the lack of strict mode had unexpected results:
- Url matching needs to be done on `url.href` see aa58b354a4
- Null and undefined are not the same thing, there were a few cases of this being confused
- Particularly questionable changes in [PostExporter tests](c1a468744b) tracked [here](https://github.com/TryGhost/Team/issues/3505).
- A typo see eaac9c293a
Moving forward, using assert strict should help us to catch unexpected behaviour, particularly around nulls and undefineds during implementation.
no issue
- Reduced the amount of diffeerent properties by not populating a `currentARR` and `currentMembers` fields, but use a `currentValue` instead.
- The type of milestone can still be determined by its `type` property, so we actually don't need two different props here

- Added a `slack-notifications` repository which handles sending Slack
messages to a URL as defined in our Ghost(Pro) config (also includes a
global switch to disable the feature if needed) and listens to
`MilestoneCreatedEvents`.
- Added a `slack-notification` service which listens to the events on
boot.
- In order to have access to further information such as the reason why
a Milestone email hasn't been sent, or the current ARR or Member value
as comparison to the achieved milestone, I added a `meta` object to the
`MilestoneCreatedEvent` which then gets accessible by the event
subscriber. This avoid doing further requests to the DB as we need to
have this information in relation to the event occurred.
