Custom headers on HTTP-Out

[brechtvdv]

It would be nice to configure custom headers (e.g. API_KEY) on the HTTP-out connector.
This would allow to run LDIO integrations external from Urban Sense.

We can resolve this issue by also using the 'request-executor' in this module

@brechtvdv do you only need this for the api key or for other custom headers as well?

I made a small change that makes it possible to add the following config for the api key:

        auth:
          type: API_KEY
          api-key: my-secret
          api-key-header: x-api-key

Other custom headers are not possible yet but we are looking to add that functionality as well
