* `doh_method` **GET|POST**, whether to use GET or POST http method for DoH requests (defaults to POST).
* `max_idle_conns` **INTEGER**, maximum number of idle connections to cache per upstream for reuse.
Default is 0, which means unlimited.
* `read_timeout` **DURATION**, the per-query read timeout applied to each upstream when waiting for a
response. The default is 2s. Increase this if upstreams legitimately take longer than 2s to answer
(for example slow recursive resolutions that would otherwise surface as `SERVFAIL`/timeouts). Note
that this timeout applies to each upstream individually, so large values reduce the time available
to retry other upstreams within a single query.
* `tls` **CERT** **KEY** **CA** define the TLS properties for TLS connection. From 0 to 3 arguments can be
provided with the meaning as described below
