Create a read-only permission set

**Is your feature request related to a problem? Please describe.**
When accessing the API we are using the same credentials as a user.
This can create a big security concern when using a privileged user with read & write permissions.

**Describe the solution you'd like**
Create a set of permissions that allows the same level of **read** access as a super admin but without any write access.

**Describe alternatives you've considered**
Access to the API could be done using an API key instead of a normal account but the set of permissions is still necessary.
