feat: hide `system.queries` table from prod by default (#7810)
Introduce a new header called `iox-debug` which when set enables certain
debug features. The first one will be the `system.queries` table which
is a process-local, namespace-scoped query log. In most prod setups this
is only useful for debugging and will confuse the user a lot because
when multiple queries are deployed then the K8s routing decides which
pod/process the users hits. This leads to an inconsistent view. However
the log is still useful for debugging.

This also wires the "debug header set" flag through the Flight ticket,
because JDBC proved (integration tests FTW!) that headers are only
passed to `GetFlightInfo` but not to `DoGet` and the ticket must encode
all the relevant information.

Closes #7119.
