Wez Furlong e9868287b3 tsa: remove accidental single threaded constraint
Explicitly spawn via the main tokio runtime when starting the http
listener for TSA, so that the tasks spawned by axum are also spawned
there.

Previously, it would stick to whichever localset thread was used for
initializing the lua context, constraining all http request decoding and
dispatching to that same thread.

With this change in place, in the NOP (stale log record) case I can get
180k qps, this is likely as fast as it will go on this particular
machine, as it is 100% CPU bound on all cores.

With a current log record I can get 90k qps.  In that case, the sqlite
performance is the limiting factor and the cores are around 70-80%
saturated.

For comparison, the rate I get with 2024.11.22-17fafff1 is 27k qps, so
this series of commits overall represents a 3.3x improvement in
performance.

Note that the http server spawning change may also benefit kumod's http
injection API.  I deliberately left that as it was because it is worth
being deliberate about benchmarking that before just shipping the same
change--kumod has an http injection pool to explicitly manage
performance and care should be taken to evaluate the impact on that.

KumoMTA

KumoMTA is an open-source Message Transfer Agent (MTA) designed for high-performance outbound email functionality, similar to commercial enterprise MTAs such as Momentum, PowerMTA, and Halon.

The KumoMTA project was founded by a group of email industry veterans with decades of experience building and managing high-performance On-Prem MTAs and is supported by a community of some of the largest senders in the world.

Because it is designed for high-performance sending environments, KumoMTA is for experienced email operations professionals who are accustomed to high-performance sending environments and familiar with DevOps practices.
