    Add enabled condition for read-only address pools

    This condition will disable the address pools row dropdown
    menu for address pools created before bootstrap which are
    read-only and leave them enabled for address pools created
    post bootstrap which are not read-only.

    Test Plan:
    PASS: Build python-django-horizon package with these changes
     and install it in a system. Verify the changes are applied
      correctly.
    PASS: Build iso with these changes and perform a fresh
    install. Verify the changes are applied correctly.
