Add role for developer user to access resources on default namespace

[anjannath]

Without this role added, we get the following error when using the crc-developer context:

% oc project
error: you do not have rights to view project "default" specified in your config or the project doesn't exist

% oc get all -n default
Error from server (Forbidden): pods is forbidden: User "developer" cannot list resource "pods" in API group "" in the namespace "default"
Error from server (Forbidden): replicationcontrollers is forbidden: User "developer" cannot list resource "replicationcontrollers" in API group "" in the namespace "default"

After adding the role, rolebinding developer user is able to access resources on the namespace:

% oc get all -n default
