HTTP specification for the TRACE method states that Squid should reflect the HTTP Request message (sans content and sensitive details). This change allows admin to supply a custom template file that will be used instead to generate TRACE responses.

HTTP specification for the TRACE method states that agents
such as Squid should reflect the HTTP Request message headers.
With certain sensitive headers filtered out.
Allow admin to adjust the TRACE output by supplying a custom
template file called HTTP_TRACE_REPLY that will be used to
generate TRACE responses.
The template will be expanded the way Squid error pages are,
allowing any macro/code available on those templates to also
work for TRACE.
The default Squid generated response is equivalent to a template
containing only the %R code.
