Add a command line to to run yaml-tests from stdin.

A console-script reads stdin and generates a TestSuite to be run.
This can be used as a nice way to test running services without any
test-building-in-python requirements.

+    This command provides a way to run a set of tests encoded in YAML that
+    is provided on STDIN. No fixtures are supported, so this is primarily
+    designed for use with real running services.
+
+    Host and port information may be provided in two different ways:
+
+    * In the URL value of the tests.
+    * In a `host` or `host:port` argument on the command line.
+
+    An example run might looks like this::
+
+        gabbi-run example.com:9999 < mytest.yaml
+
+    Output is formatted as unittest summary information.
