Max seats from prioriy & fairness work estimator is now min(0.15 x
nominalCL, nominalCL/handSize)
'Max seats' calculated by work estimator is currently hard coded to 10.
When using lower values for --max-requests-inflight, a single
LIST request taking up 10 seats could end up using all if not most seats in
the priority level. This change updates the default work estimator
config such that 'max seats' is at most 10% of the
maximum concurrency limit for a priority level, with an upper limit of 10.
This ensures seats taken from LIST request is proportional to the total
available seats.

Serving profiling information can leak information or expose the
apiserver to possible DoS attacks. Serving on a UDS is more secure
though slightly less convenient. One can't use `go tool pprof` directly
against the socket since it's not supported, but can either run a proxy
to copy from the socket over to http, or use `curl --unix-socket` to
download the profile and then use `go tool pprof`.

the new field exists primarily to avoid returning a 404 response when a resource actually exists but we haven't installed the path to a handler.
it is exposed for easier composition of the individual servers.
the primary users of this field are the WithMuxCompleteProtection filter and the NotFoundHandler.

add a new mode for graceful termination with the new server run option
'shutdown-send-retry-after'
- shutdown-send-retry-after=true: we initiate shutdown of the
HTTP Server when all in-flight request(s) have been drained. during
this window all incoming requests are rejected with status code
429 and the following response headers:
- 'Retry-After: N' - client should retry after N seconds
- 'Connection: close' - tear down the TCP connection
- shutdown-send-retry-after=false: we initiate shutdown of the
HTTP Server as soon as shutdown-delay-duration has elapsed. This
is in keeping with the current behavior.
