Add pretty printing for the data retrieved through the Gitlab API's

fansi by Li Haoyi might be of some use here.

Ideally the pretty printing of data should be in some form of ASCII table. Pipeline status should have coloured output depending on its value.

Ideally the pretty printing should be lifted into a reusable function that allows for configuration. Configurable parts of the function should be e.g.

• Number of columns
• Width of each column
• Header fields for each column (extract from case class???)
• ???
