Get user permissions

This API returns a list of permissions for the user that is currently logged in.

Example: Assume the following RBAC policy, and users alice and bob:

p, role:dev, namespaces, read, *
p, role:dev, database-engines, *, */*
p, role:dev, database-clusters, *, */*
p, bob, database-clusters, *, */*
g, alice, role:dev

The API will return the following permissions for alice:

{
  "permissions": [
    [
        "alice",
        "namespaces",
        "read",
        "*"
    ],
    [
        "alice",
        "database-engines",
        "*",
        "*/*"
    ],
    [
        "alice",
        "database-clusters",
        "*",
        "*/*"
    ]
  ]
}

And the following permissions for bob:

{
  "permissions": [
    [
        "bob",
        "database-clusters",
        "*",
        "*/*"
    ]
  ]
}
