@jpjpjp - Can you please review

@jeremywillans, I had to modify what you did in order for it to work. The FedRamp toggle was not being passed to the SDK properly so wasn't initializing using proper service URLs.

This is what I did in the framework.js file that allowed it to work correctly.

    let config = {
      config: {
      },
      credentials: {
        access_token: this.options.token
      }
    };
    // add fedramp param if defined
    if (this.options.fedramp) {
      config.config.fedramp = true;
    }

What I'm not sure of is if this will cause issues with other options. webhookUrl and port still work fine but not sure about the others.
