compute_ctl: Add OTEL tracing to incoming HTTP requests and startup (#10971)

Browse Source 
We lost this with the switch to axum for the HTTP server. Add it back.

In addition to just resurrecting the functionality we had before, pass
the tracing context of the /configure HTTP request to the start_postgres
operation that runs in the main thread. This way, the 'start_postgres'
and all its sub-spans like getting the basebackup become children of the
HTTP request span. This allows end-to-end tracing of a compute start,
all the way from the proxy to the SQL queries executed by compute_ctl as
part of compute startup.
