Add dashboard with User Task Bottleneck detection visualizations to default templates

What is the desired functionality that you are missing?

I want to be able to create a bottleneck detection dashboard with a single click

Which problem are you going to solve with this functionality?

New Optimize users don't know how to create effective reports and dashboards. As a result, Optimize tends to be under-utilized. This template provides the ability for users to create a dashboard for bottleneck analysis (a core workflow). It accompanies the related blog post (https://docs.google.com/document/d/1xwDkeNNmniiZxVQvUrhg4O5FszF6McmqYiMJa6Ov9k4/edit#).

Context: Given, When, Then

GIVEN I am creating a new dashboard
THEN an option to create a User Task Bottleneck dashboard is provided
WHEN I create a User Task Bottleneck dashboard
THEN I can see reports for

• Where is my bottleneck? (view user task count, group by user task, filter to show flow nodes with an assignee of "unassigned", visualize as heatmap)
• How bad is my bottleneck? (view user task average duration for total, work, and idle, grouped by user task, visualize as heatmap)
• Who's contributing to my bottleneck? (view user task average duration, grouped by assignee, distribute by user task, filter flow nodes by assignee is not unassigned, visualize as stacked bar chart)
• Is the bottleneck improving? (view process instance average duration, group by end date auto, visualize as bar chart)
• Are user tasks becoming more efficient? (view user task work and idle duration, group by end date auto, filter to exclude ????)
• Is work smoothly delivered to the bottleneck? (TODO: Filter Process Instances by Flow Nodes running before the bottleneck) (view process instance count, filter by start flow node, visualize as number)
• How many tasks are waiting at my bottleneck? (To Do: Edit the filter to select the flow node AT the bottleneck) (view process instance count, filter by start flow node and assignee is unassigned, visualize as number)
• How productive are my workers? (view user task count, group by assignee, distribute by user task, filter by flow node state-completed, filter by user task end date-last month, visualize as stacked bar chart)
• How long does each user task take? (view user task duration (average and median), group by user tasks, filter by start date within the last month)
