closes ENG-632
- This listens to a new property in the `milestones` config to set a minimum value of Milestones we wanna use the Slack notification service for

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.
- by default, got retries failed requests, which is causing issues in
tests because we've disabled the network with `nock`
- this is causing huge idle time because got pauses before retrying
- this change disables the retries if we're running tests, so things are
more stable

- When milestones will be activated we would send out emails to users
that are way above the achieved milestone, as we didn't record
milestones before
- The plan is to implement a 0 milestone and don't send an email for
achieving those and also add all achieved milestones in the first run
until a first milestone is stored in the DB, then increment from there.
- This change takes care of two cases:
1. Milestones gets enabled and runs initially. We don't want to send
emails unless there's already at least one milestone achieved. For that
we add a 0 milestone helper and add a `initial` reason to the meta
object for the milestone event, so we can choose not to ping Slack and
also disable email sending for all milestones achieved in this initial
run.
2. All achieved milestones will be stored in the DB, even when that
means we skip some. This introduces the `skipped` reason which also
doesn't send emails for the skipped milestones, but will do for
correctly achieved milestones (always the highest one).
- Added handling for slack notifications to not attempt sending when
reason is `skipped` or `initial`
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.
