- added request queueing middleware (express-queue) to handle high
request volume
- added new config option `optimization.requestQueue`
- added new config option `optimization.requestConcurrency`
- added logging of request queue depth - `req.queueDepth`
We've done a fair amount of investigation around improving Ghost's
resiliency to high request volume. While we believe this to be partly
due to database connection contention, it also seems Ghost gets
overwhelmed by the requests themselves. Implementing a simple queueing
system allows us a simple lever to change the volume of requests Ghost
is actually ingesting at any given time and gives us options besides
simply increasing database connection pool size.

- at this point, we have no real reason to keep this behind as it wasn't
proven what the cause of the high CPU was, and it's just causing more
lockfile issues with the resolution

- bumps Koenig packages to version containing a fix to our denest transform so it properly handles denesting element nodes inside list item nodes
