If a job is still running when the gantt chart is generated, the job's
phases won't be represented as a bar on the chart.
To show these jobs on the gantt chart, introduce a new phase "In-Progress"
to capture the current status of these jobs. Rename the "Running" phase
as "Time spent running" to emphasize that the running phase is complete.
This provides a more complete picture of the pipeline jobs when CI times
out.
