Transact literal should accept EDN and Transit as well as JSON

[mtnygard]

Description

Expected Behavior

Vase literals should be consistent in their allowed inputs. Any of them that take data in (e.g., query and transact) should accept all the data-like representations we support:

• JSON
• EDN
• Transit

Actual Behavior

The transact literal only accepts JSON payloads.

Environment

Pedestal and Vase version

Vase 0.9.1

I would love to see transit-params support since transit is much more superior than json and we already use it as standard protocol in many of our services.
