Update Caddy to v0.10.13 so that environment variables may be used after
Go template (e.g. in template's answer). v0.11.0 has been released, but
v0.10.13 is a smaller set of changes and has the necessary fix.

Fixes #2153

else than "present in map" any way.

This removes a bunch of appends to where not needed, makes dnsutil.Join

* - ensure plugins that use prometheus.MustRegister, re-register after reload
- removing once.Do on the startup function was simplest way to do it.

* - fix underscored names (advice of bot)

* - tune existing UT for reload, and add a test verifying failing reload does not prevent correct registering for metrics

* - ensure different ports for tests that can run in same time ..

* Move functions from pkg/transport to pkg/parse

Although "parse" is a fairly generic name I believe this is somewhat
better named. pkg/transport keeps a few constants that are uses
throughout for the rest is is renaming a bunch (and the fallout from
there to make things compile again).

* Fix tests
Signed-off-by: Miek Gieben <miek@miek.nl>

Create plugin/pkg/transport that holds the transport related functions.
This needed to be a new pkg to prevent cyclic import errors.

This cleans up a bunch of duplicated code in core/dnsserver that also
tried to parse a transport (now all done in transport.Parse).

* [plugin/proxy]: Return on WriteMsg err.

Followup PR on the heels of #2050. Short-circut and log on error from
`WriteMsg`. This will prevent code getting stuck on `ReadMsg` and allow
for easier debugging.

Also simply the `ReadMsg` calling code a little - remove double `Close` (already called above).
