Preparing repository for splitting cookbooks into their own repos.

* Add a CONTRIBUTING file to each cookbook.
* Move the Changes/Roadmap section(s) to CHANGELOG.md.
* Create the Apache LICENSE file in each cookbook.

CONTRIBUTING

@@ -0,0 +1,29 @@
+If you would like to contribute, please open a ticket in JIRA:
+
+* http://tickets.opscode.com
+
+Create the ticket in the COOK project and use the cookbook name as the
+component.
+
+For all code contributions, we ask that contributors sign a
+contributor license agreement (CLA). Instructions may be found here:
+
+* http://wiki.opscode.com/display/chef/How+to+Contribute
+
+When contributing changes to individual cookbooks, please do not
+modify the version number in the metadata.rb. Also please do not
+update the CHANGELOG.md for a new version. Not all changes to a
+cookbook may be merged and released in the same versions. Opscode will
+handle the version updates during the release process. You are welcome
+to correct typos or otherwise make updates documentation in the
+README.
+
+If a contribution adds new platforms or platform versions, indicate
+such in the body of the commit message(s), and update the relevant
+COOK ticket. When writing commit messages, it is helpful for others if
+you indicate the COOK ticket. For example:
+
+    git commit -m '[COOK-1041] Updated pool resource to correctly delete.'
+
+In the ticket itself, it is also helpful if you include log output of
+a successful Chef run, but this is not absolutely required.
