Introduce blob representation to Active Storage

Returns an ActiveStorage::Preview instance to preview a blob, or an ActiveStorage::Variant instance for an image.

Safer redirect_back method

The allow_other_host can now block redirects to a different host. The option is true by default to make it backward compatible.

Fix Active Support cache clean up

Rails was using the stored keys to remove files, instead of the filenames.

Fix Active Job to yield error when rescheduling fails

The retry_on method now yields the actual error to the block instead of the exception class.
