Removed :if and :unless from fragment cache option in favour of

cache_if(condition, option, &block) and cache_unless(condition, option, &block).

In the PR #8371 was introduced  conditional options :if and :unless in
the cache method.

    Example:

      <%= cache @model, if: some_condition(@model) do %>
        ...
      <%end%>

This is a good feature but *cache_if* and and *cache_unless*
are more concise and close to the standard of rails view helpers
(ex: link_to_if and link_to_unless).

    Example:

      <%= cache_if condition, @model do %>
      ...
      <%end%>
