Merge pull request #1044 from octodns/yaml-provider-refactor

Deprecate SplitYamlProvider, subsume functionality into YamlProvider w/a refactor

 * New dynamic zone config support that allows wildcard entries in the octoDNS
   config to be expanded by the source provider(s). See
   [Dynamic Zone Config](/README.md#dynamic-zone-config) for more information.
+* SplitYamlProvider has been deprecated and will be removed in 2.0. YamlProvider
+  now includes the ability to process split zones when configured to do so and
+  allows for more flexibility in how things are laid out than was previously
+  possible. This includes the ability to split some zones and not others and
+  even to have partially split zones with some records in the primary zone YAML
+  and others in a split directory. See YamlProvider documentation for more info.

+    -------------
+
+    All files are stored in a subdirectory matching the name of the zone
+    (including the trailing .) of the directory config. It is a recommended
+    best practice that the files be named RECORD.yaml, but all files are
+    sourced and processed ignoring the filenames so it is up to you how to
+    organize them.
+
+    With `split_extension: .` the directory structure for the zone github.com.
+    managed under directory "zones/" would look like:

+    zones/

+
+    Overriding Values
+    -----------------
+
     Overriding values can be accomplished using multiple yaml providers in the
     `sources` list where subsequent providers have `populate_should_replace`
     set to `true`. An example use of this would be a zone that you want to push
