These methods will be used by the Mailgun implementation of EmailSuppressionList
so that emails are removed from both our internal list and Mailguns.

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.

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.

- see referenced issue for more context but Ghost sometimes has issues
with the email analytics job getting stuck
- we don't provide a timeout to the Mailgun library, so we just
sit there idling for eternity if something between us and Mailgun is
causing issues
- this commit adds a 60s timeout so we can at least error out and try
again next time
- during a refactor, I moved the `BATCH_SIZE` variable around
- putting the variable export above a more general export means it get
overwritten and the value is `undefined` outside of the module
- when we chunk the emails, we were chunking in sized of `undefined`,
so I'm guessing it just defaulted to 1
- this means the email batches were of size 1 instead of 1000 - oops
refs https://github.com/TryGhost/Toolbox/issues/363
- this commit switches us to using the official and maintained
`mailgun.js` SDK, and updates the `mailgun-client` code to reflect the
changes between the two
- when I extracted `mailgun-client` to a separate package, I
accidentally removed the lazyloading for the `mailgun-js` library,
which takes a non-negligible amount of time to require on boot
- this fixes that by moving the require into the function where it's
used
- even though we don't do anything yet, the code was calling `.length`
on an object, which is `undefined`
- this fixes that by checking the length of the keys
- also moves the code block down so we can early-return if mailgun is
not configured
refs https://github.com/TryGhost/Toolbox/issues/363
- 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
