Rename to opa-docker-authz and bump version

Also, set TLS configuration to nil when starting the Docker SDK. The API was
updated since the last release.

 This project is used to show how OPA can help policy-enable an existing service.

 To build the plugin, just run:
 
     $ go get ./...
-    $ go build -o docker-authz-plugin
+    $ go build -o opa-docker-authz
 
 This assumes you are running on Linux and have Go 1.6 or later on your machine. You must have $GOPATH set.
 
 If you are running on OS X and want to cross compile for Linux, you can do so as follows:
 
-    $ docker run -it --rm -v $PWD:/go/src/github.com/open-policy-agent/docker-authz-plugin golang:1.6 bash
-    $ cd /go/src/github.com/open-policy-agent/docker-authz-plugin/
+    $ docker run -it --rm -v $PWD:/go/src/github.com/open-policy-agent/opa-docker-authz golang:1.6 bash
+    $ cd /go/src/github.com/open-policy-agent/opa-docker-authz/
     $ go get ./...
-    $ go build -o docker-authz-plugin
+    $ go build -o opa-docker-authz
     $ exit
 
 ### Install
 
 The plugin can be started with no options. It may require sudo depending on your machine's Docker configuration permissions:
 
-    $ docker-authz-plugin
+    $ opa-docker-authz
 
 - By default, the plugin will listen for requests (from Docker) on :8080 and contacts OPA on :8181.
 
 The following command line argument enables the authorization plugin within Docker:
 
-    --authorization-plugin=docker-authz-plugin
+    --authorization-plugin=opa-docker-authz
 
 On Ubuntu 16.04 this is done by overriding systemd configuration (requires root):
 
     $ sudo mkdir -p /etc/systemd/system/docker.service.d
     $ sudo tee -a /etc/systemd/system/docker.service.d/override.conf > /dev/null <<EOF
     [Service]
     ExecStart=
-    ExecStart=/usr/bin/docker daemon -H fd:// --authorization-plugin=docker-authz-plugin
+    ExecStart=/usr/bin/docker daemon -H fd:// --authorization-plugin=opa-docker-authz
     EOF
     $ sudo systemctl daemon-reload
     $ sudo service docker restart
