Bug: oc should be included

[kyetter]

Description

For the oc_connection molecule demo, once molecule prepare is run, the user needs to run "source ~/.bashrc" to have oc recognized on the path. Jeff proposed 3 options for getting rid of this:

• include oc in the container image
• include oc in the dev file so that its downloaded and stored somewhere already in the path
• put together some shell script in the image that is executed (hopefully automatically on launch)
