beam 3317 - use proper embed process

[cdhanna]

Ticket

https://disruptorbeam.atlassian.net/browse/BEAM-3317

Brief Description

We got a whacky exception from embed io, and looking at their github page, I found this
unosquare/embedio#570

And the critical part is...

use of HttpContext.SendDataAsync(), which must never be called from a WebApiModule.

But we do that... Sooooo, maybe we should not. So this PR changes the structure to follow their documentation described here
