[estimate] Create list estimate page

In the RY page, next to Traceability tab, add an Estimate Tab.

Like the traceability matrixes, it will have 3 sublists + a button "Create new":

• Private,

• Shared by you

• Shared by others

The list shows, for each line:

• a name → Yes (a label/title)

• an edit button → Yes - which displays a dialog to edit the label and permissions (ie if a user wants to edit the matrix, they should click on the label).

• a remove button → Yes

• a preview of the estimated contained in a row ? → No

• a reorder handle → No (not yet)

• List is empty if nothing had been created (thank you cap'tain obvious) → No, see “welcome experience” below

• as traceability matrix, the config is stored in database (to be defined what is stored)

• Be careful to who has the permission to see/create/edit/remove those information

→ It is effectively exactly the same screen as the traceability matrixes, certainly we should only reuse the .vm.

Empty list (the welcome experience)

If “Private” is empty, we will:

• Use the “.blank-experience-container”

• Saying “You haven’t created any estimate yet.” with a button “Create one!”

If the other lists are empty, we just don’t display them.
