experimentClient.fetch() always uses 10s to resolve #185
Description
When ExperimentClient is created by initializeWithAmplitudeAnalytics, experimentClient.fetch() always uses 10 seconds to resolve, even if the request is blocked and retry is disabled.
It would be great if experimentClient.fetch() could resolve as soon as the outcome is known, either successful or failure.
Currently, even if the request itself fails, it keeps waiting for AmplitudeIntegrationPlugin.setup to complete.
I created #184 as a sort of band-aid for at least not waiting a full 10s.
