* plugin/forward: remove dynamic read timeout

We care about an upstream being there, so we still have a dynamic dial
time out (by way higher then 200ms) of 1s; this should be fairly stable
for an upstream. The read timeout if more variable because of cached and
non cached responses. As such remove his logic entirely.

Drop to 2s read timeout.

* Set SOA record TTL as min of TTL/MINIMUM

According to
https://tools.ietf.org/html/rfc2308#section-3:

  The TTL of this record is set from the minimum
  of the MINIMUM field of the SOA record and the
  TTL of the SOA itself, and indicates how long a
  resolver may cache the negative answer.

Set the TTL accordingly so as to not always
negative cache SOA records for 300 seconds.

* Inline min func

* Update SOA record tests

* Fix types

* Redo the plugin log PR

Remove the code duplication and call of the "official" functions. This
is the second(?) time we forgot to update the other half, so remove that
problem entirely.

Also add a test if the correct (within limits) time in front of the log
line.

* Add email

* Add my affiliated organization (Infoblox)

* Add email next to my github handle

Following Governance description, I add my email next to my github handle.

I would need for CNCF Graduation to show the different organizations the maintainers are from. Anyone with no email or personal email (like gmail) will be considered under its own organization.

That would also help when vote will come-in, as we restraint votes for people on the same organization.

@miekg :
* I guess that will need change in the dreck project that parse this file.
* Do you want me to PR the change on that project (miek/dreck) ?

Default to using pkg/log for all logging and use a fixed time prefix
which is RFC3339Millli (doesn't exist in time, so we just extended
RFC3339), i.e. Nano might be pushing it.

When fetching records via the etcd plugin, the recursion flag was never
set properly according to if the caller requested an exact record match
or not. This cause problems especially in CNAME lookups, where recursion
took place and a random RR was returned instead of the one that was
specifically added for this key. Even when there is no service attached
on the given path, it is still wrong to return a random one from the
recursion.

Fixing by using the `exact` flag to decide if recursion should be done.

This reverts commit 8045aa27.

Remove some optimization and lowercasing of the qname (in the end
miekg/dns should provide a fast and OK function for it).

* remove the make([]byte, 2) allocation in the key()
* use already lowercased qname in hash key calculation.
