Make Zencoder URLs interpolation pattern configurable

Pass `:url`, `:hls_url` and `:hls_origin_url` from `zencoder_options`
set in initializer to `ZencoderAttachment.default_options`.

Allows to override the interpolation pattern used to construct urls to
Zencoder generated files. Previously only available for the :path
option.
