Remove the required obscuring of strings from the generate endpoint

[SteveDMurphy]

Is your feature request related to a specific problem?

The gymnastics involved with string compression and encoding between the client and the server make this pretty hairy to do.

As a measure to keep the front end moving along at speed, proposing to remove this functionality.

With protected endpoints and SSL, this should render the obscuring to be moot anyways. The risk has always been for people not implementing SSL when deploying fides

Describe the solution you'd like
