More fine granular OpsManger roles for API CRUD operations

In order to generate API Keys users need some pretty powerful role https://docs.opsmanager.mongodb.com/current/reference/api/org-api-keys/. Same for project API Keys https://docs.opsmanager.mongodb.com/current/reference/api/project-api-keys/.

Our understanding is that user who can create api keys could also self promote themselves to super admins which is something we don't want and would be a security concern to us. (And admins normally have access to far more things than just user mgmt)

Additionally it would be beneficial to pass in an desired api key - e.g. for initial provisioning and give admins the chance to reset/rotate an API Key.

This would boil down two these two request for enhancements:

1. As a user who's logged into Ops Manager, I can generate an API token for myself without having project admin rights
2. As an Ops Manager Admin user, I can pass in a username and desired api key into the OpsManager API
