The methods `fresh_when` and `stale?` from ActionController::ConditionalGet
accept a single record as a short form for a hash. For instance
```ruby
def show
@article = Article.find(params[:id])
fresh_when(@article)
end
```
is just a short form for:
```ruby
def show
@article = Article.find(params[:id])
fresh_when(etag: @article, last_modified: @article.created_at)
end
```
This commit extends `fresh_when` and `stale?` to also accept a collection
of records, so that a short form similar to the one above can be used in
an `index` action. After this commit, the following code:
```ruby
def index
@article = Article.all
fresh_when(etag: @articles, last_modified: @articles.maximum(:created_at))
end
```
can be simply written as:
```ruby
def index
@article = Article.all
fresh_when(@articles)
end
```
