Artem Boldariev 51a2c7aed3 DoH: Set the "max-age" "Cache-Control" HTTP header value 
This commit makes BIND set the "max-age" value of the "Cache-Control"
HTTP header to the minimal TTL from the Answer section for positive
answers, as RFC 8484 advises in section 5.1.

We calculate the minimal TTL as a side effect of rendering the
response DNS message, so it does not change the code flow much, nor
should it have any measurable negative impact on the performance.

For negative answers, the "max-age" value is set using the TTL and
SOA-minimum values from an SOA record in the Authority section.
