the current update frequency for the refresh loop in the route 53 plugin is hard-coded
to 1 minute. aws rate-limits the number of api requests so less frequent record refreshes
can help when reaching those limits depending upon your individual scenarios. this pull
adds a configuration option to the route53 plugin to adjust the refresh frequency.
thanks for getting my last pull released so quickly. this is the last local change that
i have been running and would love to get it contributed back to the project.

Various fixes to make things less flaky:
* kubernetes: put klog.SetOutput in the setup function, not in the init
function to see if that helps
* file: make z.Expired a boolean instead of a pointer to a boolean
* test: fix TestSecondaryZoneTransfer test, which wasn't actually
testing in the right way. It's more right now, but may still be racy
(race introduced because a file's lazy loading of zones)

* plugin/hosts: create inline map in setup
The inline map wasn't create in the setup.go fuction leading to a crash,
which is masked by a recover (but leads to a SERVFAIL, and not logging
the request).
Various other simplifications.
host plugin could use some test that actually cover these edgecases.

without the paging parameter set, it will default to 100 records per request. with large enough zones and
potentially multiple coredns daemons configured to pull from route 53, this can quickly add up and reach
aws global api rate limits (5/sec per root account). increasing paging to max can help reduce the number
of requests needed to pull records for a zone without no down side that i am aware of.
this helps issue #2353, but probably is not a complete fix.

These are too hidden now. They increase the issue-load, because people

I don't believe this is actually needed (anymore). The:

New plugins are usually dropped in one giant ball of code, add some

The host plugin kept on adding entries instead of overwriting. Split the
inline cache off from the /etc/hosts file cache and clear /etc/hosts
file cache and re-parsing.
A bunch of other cleanup as well. Use functions defined in the plugin
package, don't re-parse strings if you don't have to and use To4() to
check the family for IP addresses. Fix all test cases a carried entries
are always fqdn-ed. Various smaller cleanup in unnessacry constants.
Fixes: #3014

* plugin/file: simplify locking
Simplify the locking, remove the reloadMu and just piggyback on the
other lock for accessing content, which assumes things can be move
underneath.
Copy the Apex and Zone to new vars to make sure the pointer isn't
updated from under us.
The releadMu isn't need at all, the time.Ticker firing while we're
reading means we will just miss that tick and get it on the next go.
Add rrutil subpackage and put some more generic functions in there, that
are now used from file and the tree package. This removes some
duplication.
Rename additionalProcessing that didn't actually do that to
externalLookup, because that's what being done at some point.
