Improve dev tooling (OSC#1305)

improve dev container experience

This adds a `dev` namespace to our rake tasks and documentation around those tasks.  Running `dev:start` will build and start a development container with your UID & GID with password that you can set.

+# Developing Open-OnDemand
+
+## Getting Started
+
+These are instructions to build and interact with a full stack
+development container.  This container will create a duplicate user
+with the same group and user id.  Starting the container will prompt  
+you to set a password.  This is only credentials for web access to the
+container.
+
+Pull down this source code and start the container.
+
+```text
+mkdir -p ~/ondemand
+git clone https://github.com/OSC/ondemand.git ~/ondemand/src
+cd ~/ondemand/src
+rake dev:start
+```
+
+See `rake --tasks` for all the `dev:` related tasks.
+
+```
+rake dev:exec                               # Bash exec into the development container
+rake dev:restart                            # Restart development container
+rake dev:start                              # Start development container
+rake dev:stop                               # Stop development container
+```
+
+### Login to the container
+
+Here's the important bit about user mapping with containers. Let's use the
+example of `jessie` with `id` below. In creating the development container,
+we added a user with the same.  The password is for `dex` the IDP, and the
+web only. 
+
+```
+uid=1000(jessie) gid=1000(jessie) groups=1000(jessie)
+``` 
+
+Now you'll be able to access `http://localhost:8080/` where it'll redirect
+you to `dex` the OpenID Connect provider within the container. Use the email
+`<your username>@localhost`.
+
+
+### Configuring the container
+
+In starting the container, you may see the mount 
+`~/.config/ondemand/container:/etc/ood`.  This mount allows us to
+completely configure this Open-OnDemand container.
+
+Create and edit files in the host's home directory and to mount in
+new configurations. 
+
+Remove `~/.config/ondemand/container/static_user.yml` to reset your
+container's password.
+
+### Rebuilding the image
+
+All the development tasks will use the `ood-dev:latest` image.  If
+you want to rebuild to a newer version use the rebuild task.
+
+```text
+rake dev:rebuild
+```
