AV Digestor correctly passes format to LookupContext

ActionView::Digestor now passes arguments correctly to
LookupContext::find method. This makes cache digests
respect the format option correctly.

FixtureFinder in tests also changed to reflect this.
Add support for extra options to `force_ssl`

This commit adds support for passing additional url options along
with a :status option and any of the flash-related options to
`redirect_to` (i.e. :flash, :alert & :notice).

Closes #7570.
