operation: OpenID Connect authentication

[johnandersen777]

We we want here is to make operations which can do the OpenID connect flow. So that users can make dataflows which have authentication.

We should support the OpenID connect protocol to leverage accounts users already have with other services to authenticate them (aka the Authorize X service page from github).

The oidcrp library seems promising.

I think we'll need this:

for testing you'll want to add the operations under a route similarly to how the dataflow http deployment use case works.
