Change "Churn rate is low" question and description

[sunilj0lly]

This should be:
"Change is well managed"

The description should be:
"When the project changes, the change is handled with appropriate workflows and is not a knee jerk reaction".

Note - this change can be done in the database and any retrospectives with the existing "churn rate is low" question should stay as they are.

Instead of changing this in the DB, we should create a page where you can create questions and assign those to a question set which can be used for Retrospectives.

I suggest the following could work:

• Can create/edit/delete a question
• Can created/edit/delete a question set, which has at least 1 question and no limit on the max number of questions. A question set has two sections "Project Health" and "Project Smells Check" and a question can be assigned to one of these sections (these are displayed as different sections in the form. Note - a piece of work in the future could be to enable section creation but I don't think this is needed right now)
• Can select a question set to use when creating a retrospective.
• If there is only a single question set, then there is no select option when creating a new retrospective.
• Once a question set is applied to a retrospective it cannot be changed (the retrospective will need to be deleted and a new one created)
• Once a question set is applied, editing the questions or the question set does not affect that retrospective.
