The protocol policies were not taking the default roles work
we did last release into account. This commit changes the default
policies to rely on the ``reader`` role for get and list protocols.
Subsequent patches will incorporate:
- system member test coverage
- system admin functionality
- domain users test coverage
- project users test coverage
