Saves events in the database and collects error information.
Do note that we can emit the same events multiple times, and as a result
out of order. That means we should correctly handle that a delivered
event might be fired after a permanent failure. So a delivered event is
ignored if the email is already marked as failed. Also delivered_at is
reset to null when we receive a permanent failure.

This moves the processing of the events from the event-processor to a
new email-event-processor in the email-service package.
- The `EmailEventProcessor` only translates events from
providerId/emailId to their known emailId, memberId and recipientId, and
dispatches the corresponding events.
- Since `EmailEventProcessor` runs in a separate worker thread, we can't
listen for the dispatched events on the main thread. To accomplish this
communication, the events dispatched from the `EmailEventProcessor`
class are 'posted' via the postMessage method and redispatched on the
main thread.
- A new `EmailEventStorage` class reacts to the email events and stores
it in the database. This code mostly corresponds to the (now deleted)
subclass of the old `EmailEventProcessor`
- Updating a members last_seen_at timestamp has moved to the
lastSeenAtUpdater.
- Email events no longer store `ObjectID` because these are not
encodable across threads via postMessage
- Includes new E2E tests that test the storage of all supported Mailgun
events. Note that in these tests we run the processing on the main
thread instead of on a separate thread (couldn't do this because
stubbing is not possible across threads)
There are some missing pieces that will get added in later PRs (this PR
focuses on porting the existing functionality):
- Handling temporary failures/bounces
- Capturing the error messages of bounce events
fixes https://github.com/TryGhost/Team/issues/2282
Added a new email service package that is used when the email stability
flag is enabled. Currently not yet implemented so will throw an error
for all entry points (if flag enabled).
Removed usage of `labs.isSet.bind` across the code, because that breaks
the stubbing of labs by `mockManager.mockLabsEnabled` and
`mockManager.mockLabsDisabled`. `flag => labs.isSet(flag)` should be
used instead.
All email depending tests now disable the `emailStability` feature flag
to keep the tests passing + make sure we still run all the tests for the
old flow while the email stability package is being built.

- This change helps avoid race conditions due to a lack of a transaction
in the email job. It also moves the status check before creating the
email batches (can take a while) to prevent other timing issues in case
the job got scheduled multiple times.
- Sets the patch option to true when changing the status of an email
batch. If we don't do this, the bookshelf-relations plugin might try to
save relations too. This could have caused a 'no rows updated' error.
- Added a test that tests if the email job can only run once
- Added logging to batching logic
fixes https://github.com/TryGhost/Team/issues/2096
When generating the recipient data for emails, the email clicks
implementation is resulting in a recipient variable being added called
replacement_xxx once for each link containing the same UUID.
This generates a lot of unnecessary data overhead for emails, and it
turns out that mailgun has a 25MB message limit. We wouldn't have come
close if we only included the uuid once.

- Test is good to test if the whole flow works as expected, and works together
- We can test independent parts in separate tests that have better coverage of more edge cases
- Adds a basic helper to get an agent for the frontend (spent too much time on a better solution so I decided to keep the existing supertest agent)

- this commit pulls all code involving the Mailgun client SDK into one
new package called `mailgun-client`
- this means we should be able to replace `mailgun-js` (deprecated) with
`mailgun.js` (the new, official one) without editing code all over the
place
- this also lays some groundwork for better testing of smaller
components
refs https://github.com/TryGhost/Toolbox/issues/354
- this commit turns the Ghost repo into a monorepo so we can bring our
internal packages back in, which makes life easier when working on
Ghost
