pipeline: add ignore-rejects command

We had a mechanism to have certain images be marked as ignored, but
there wasn't a way for users to do any marking! This new command can
mark all rejected images to be ignored in the future.

+==================================
+``toasty pipeline ignore-rejects``
+==================================
+
+The ``ignore-rejects`` :ref:`pipeline command <pipeline>` marks all of the
+rejected images in a workspace to be ignored by future processing runs.
+
+
+Usage
+=====
+
+.. code-block:: shell
+
+   toasty pipeline ignore-rejects [--workdir=WORKDIR]
+
+The ``WORKDIR`` argument optionally specifies the location of the pipeline
+workspace directory. The default is the current directory.
+
+
+Example
+=======
+
+Ignore every image in the ``rejects`` directory:
+
+.. code-block:: shell
+
+   toasty pipeline ignore-rejects
+
+Subsequent invocations of :ref:`cli-pipeline-refresh` will ignore these images
+when searching for new processing candidates.
+
+
+Notes
+=====
+
+This command will ignore every image in the “reject” state.  That is, each file
+inside the ``rejects`` subfolder of the pipeline workspace will be taken to be
+an image ID that should be ignored. If you have rejects that should *not* be
+permanently ignored (maybe you can't solve their coordinates right now, but will
+be able to later), delete their files from the ``rejects`` subfolder before
+running this command.
