[APP] Amplitude Experiment Management API

**Name of app / service**
Amplitude Experiment Management API

**Link to developer documentation**
https://amplitude.com/docs/apis/experiment/experiment-management-api

An important note is this endpoint is different then the Analytics API that is currently configured as an app in pipedream. This endpoint does not require a secret-key and also is accessible at a different url base:
- Non-EU : https://experiment.amplitude.com
- EU : https://experiment.eu.amplitude.com

**Is lack of support preventing you from moving forward, or do you have a workaround?**
I can make a HTTP request, but our company (McClatchy) will be relying heavily on managing access available for connections on a per-user basis.

**Are there specific actions or triggers, you'd like to see for this app? Please let us know here or use the Action and Trigger issue templates to open requests for each!**
A generic connection will be enough for our use case.

I am not sure if integrating this with the current App makes sense because it is unclear to me how complicated it would be to make the secret-key optional for certain endpoints. No preference on my end though.
