Admin grants API management access to a team member

**USER STORY**
* As an administrator of an account
* I want to be able to grant permissions and/or a role to team members on my account
* so they can access the developer section (API access) of my account

---

**UNKNOWNS**

Is the decision here to provide another ROLE for this account or are we diving into fine-grained permissions per team member? The acceptance criteria / designs will evolve based on this (technical feasibility) decision.

---

**ACCEPTANCE CRITERIA**

* GIVEN an account has been granted API access
* WHEN an account administrator gives permission to a team member to access the developer interface of the account
* THEN the team member will be able to see and manage API keys for this account

**Design**
TBD
