In systems with very large numbers of queues, it will take an
effectively unbounded amount of time to produce the initial
summary of results if we were to wait for the bounce to be
applied to every queue.
Let's adjust the output of the kcli to indicate that it is async,
and update the docs which already suggested that the numbers would
be partial to indicate that you can only really consume the id
from the response.
There's big explanation about this in the included docs change.
The TL;DR is: we can now optionally queue the request and generate it
asynchronously wrt. the incoming injection request.
There's also a throttle that can be used to constrain this, because
the asynchronous submission disconnects the injection request from
any kind of back pressure that we'd otherwise have to indicate to
the injector that there might be load related issues.
A significant portion are bounced as they move through the queues,
not just those swept up in the direct application of the API call.
Pass in a shared hash map to track the counts and report on that
at the end of the call instead.
