Netlify-cms: maximum and minimum number of items in the list widget

[zolamk]

- Do you want to request a feature or report a bug?
Feature

- What is the current behavior?

Currently the list widget will allow us to add many list items with no virtual limit.

- What is the expected behavior?
I propose an option for the list widget that allows us to set the maximum and minimum number of items in a list.

Would really love to see this feature implemented as well.

Would also love to see this implemented. It would really help when using the Variable Types List Widget, so that the user cannot accidentally add more than 1 page template per page. Take this as an example. Without a limit on template key, the user can add more than 1 template per page in this case. You'd almost always want the option to restrict the page template to a value of 1.

collections:
  - name: Page
    label: page
    create: true
    folder: 'src/_pages/pages'
    extension: md
    slug: '{{slug}}'
    fields:
      - label: 'Title'
        name: 'title'
        type: 'string'
        default: 'Add a page'
      - label: 'Page Template'
        name: 'template'
        widget: 'list'
        types:
          - label: 'Standard Layout'
            name: 'standardLayout'
            widget: 'object'
            fields:
              - { label: 'Heading', name: 'sectionTitle', widget: 'string' }
              - {
                  label: 'Home Block Sections',
                  name: 'homeBlockSections',
                  widget: 'object',
                  fields:
                    [
                      { label: 'Heading', name: 'sectionTitle', widget: 'string' },
                      {
                        label: 'First Block',
                        name: 'firstBlock',
                        widget: 'object',
                        fields:
                          [
                            { label: 'Heading', name: 'heading', widget: 'string' },

                      },
                      {
                        label: 'Middle Block',
                        name: 'secondBlock',
                        widget: 'object',
                        fields:
                          [
                            { label: 'Heading', name: 'heading', widget: 'string' },
                            { label: 'Text', name: 'text', widget: 'text' },
                          ],
                      },
                      {
                        label: 'End Block',
                        name: 'thirdBlock',
                        widget: 'object',

                            { label: 'Text', name: 'text', widget: 'text' },
                          ],
                      },
