title: Set bearer token with OpenApi Generator
body: <p>I'm using OpenApiGenerator v5.0 beta csharp-netcore.  The configuration has ApiKeyPrefix and ApiKey, both of which are Dictionary&lt;string, string&gt;.  It seems that the token used is</p>
  <p><code>ApiKeyPrefix[&quot;Authorization&quot;] + &quot; &quot; + ApiKey[&quot;Authorization&quot;]</code></p>
  <p>Is there a way to choose which token to use?  I see Configuration.GetApiKeyWithPrefix takes a string which enables me to choose which key to inspect, but I don't see a way to choose which key to use in an individual request.</p>
