As an agile team, I want to see the time my work items spend in each status so that I can find issues and improve my working methods

Acceptance criteria:
= Can see time spent in each status in work item details
= Can report on average time in each status for all work items, by type and time range
= Can report on frequency of items in each status for all work items (bar chart version of a CFD)

Suggestions for possible solutions:
= Update the Lifecycle Workitem Cycle Time report to allow reporting on one status at a time, and
= Add report which shows time in status for all status values of a workflow, in the workflow order
= Show fractional days spent in each status


= Update Analytics "Days in Status" tracking to include fractional days, not just integer values
