Description

### Bug report

currently using 0.13.0

There seems to be only 2 kinds of users: Admin and Non-admin. Admins are the only users who can DROP series or measurements, but cannot be restricted to certain databases. Non-admin users can be restricted to certain databases, but cannot drop anything. Seems like we need a middle ground here, like a "local-admin" who can be given administrative permissions for particular databases. Otherwise we must run many InfluxDB servers in order to manage permissions in this way.

**Steps to reproduce:**

Grant all permissions to a non-admin user, try to drop a series as that user

**Expected behavior:**

I want the user to be able to drop a series or measurement, but _only_ in their specified database.

**Actual behavior:**

The non-admin user can (at most) read and write data, but not drop anything.

Research direction

Start by reviewing the authorization paths for DROP operations on series and measurements, then examine how permissions are scoped to databases. The desired outcome is a permission model that lets a non-admin drop data only in specified databases while preserving existing admin and non-admin behavior.
