To combat label cardinality explosions remove the type from metrics.
This was most severe in the histogram for request duration, remove it
there.
It's also highlighted difference between grpc and forward code, where
forward did use type and grpc didn't; getting rid of all that "fixes"
that discrepancy
Move monitor.go back into the vars directory and make it private again.
Also name it slightly better
Fixes: #4507

Cleanup a variety of metric issues.
* Eliminate department of redundancy "count_total" naming.
* Use the plural of the unit when appropriate. (ex, "requests")
* Remove label names from metric names where appropriate. (ex, "rcode")
* Simplify request metrics by consolidating type label in to the base
request counter.
* Re-generate man pages.

* Add server label and zone label for enable_plugin matric.
* Add a test for PluginEnabled metric
* Add description for enabledPlugin metric.
* Change the description for the enabledPlugin metric.
* Reset the enabledPlugin metric when restart the server.
* Add the bug session for enabledPlugin metric.
* Remove the resolveTCPAddr
* plugin/metrics: add 'server' label
This uses the new WithServer(ctx) to get the current server from the
context.
First in a larger refactor to make all plugins do this.
* compile
* compile
* lala test
* compile and test
* typos
* Dont duplicate the code
* Rename middleware to plugin
first pass; mostly used 'sed', few spots where I manually changed
text.
This still builds a coredns binary.
* fmt error
* Rename AddMiddleware to AddPlugin
* Readd AddMiddleware to remain backwards compat
