Move delivery system from Docker to RubyGems

Over time `nib` has evolved from a suite of bash scripts into a Ruby
based project wrapped up in a [GLI](https://github.com/davetron5000/gli)
gem. When we had bash scripts using Docker to distribute them was very
convenient however now that we have a gem let's take advantage of the
ecosystem around delivering (`gem install nib`) and updating them (`gem
update nib`).

 `nib` is a `docker-compose` wrapper geared towards Ruby/Rails development.

 `nib` can be used as a replacement for `docker-compose` any commands that it does not recognize will be delegated to `docker-compose`.

 1. `nib` will also hook up a history file for your shell session (relative to the current project). This means that you will be able to use the history (up arrow) in future shell sessions, something that is not available with vanilla docker/docker-compose!
 1. Finally `nib` will ensure that the container is removed after you finish with the shell session

-## Install
-
-1. The most convenient way to use nib is by creating an alias or shell function. Here is an alias you can add to your profile that will make `nib` appear as a command.
-
-    ```sh
-    alias nib='
-      docker run \
-        -it \
-        --rm \
-        -v $(pwd):$(pwd) \
-        -w $(pwd) \
-        -v $HOME/.docker:/root/.docker:ro \
-        -v /var/run/docker.sock:/var/run/docker.sock \
-        -e "DOCKER_HOST_URL=$DOCKER_HOST" \
-        technekes/nib'
-    ```
-
-1. Start a new bash session and run `nib help` to see the available commands (there may be a brief pause as the image is pulled from docker hub)
-
-## Updates
-
-To get the latest version of `nib` use the `update` command. This just pulls the latest version of `technekes/nib:latest` from the Docker Hub.
-
-```sh
-❯ nib update
-latest: Pulling from technekes/nib

 nib can help facilitate remote debugging of a running byebug server inside of a rails application. In order to make this work there are a couple of steps you'll need to take first.

-## Development
-
-While making changes to `nib` it can be helpful to run a development version to test out commands. One way to accomplish this is by building the image and creating an extra alias for the local copy.
-
-Make a change and build:
-
-```
-cd /path/to/technekes/nib
-# make some changes
-docker build --tag nibdev:latest .
-```
-
-Development alias:
-
-```sh
-alias nibdev='
-  docker run \
-    -it \
-    --rm \
-    -v $(pwd):$(pwd) \
-    -w $(pwd) \
-    -v $HOME/.docker:/root/.docker:ro \
-    -v /var/run/docker.sock:/var/run/docker.sock \
-    -e "DOCKER_HOST_URL=$DOCKER_HOST" \

-```sh
-nibdev shell web
