[orchestration] attribute for deferred_auth_method

[Ethan Lynn]

The following key needs attribute in heat.conf

# Select deferred auth method, stored password or trusts. (string value)
#deferred_auth_method = password

And it's better to set to 'trusts' by default for following reasons:

- It's more secure, we won't have to store username/password anymore
- It's better for users, because they won't have to provide a username/password anymore, e.g the box in horizon where we force them to enter a password even though horizon is already passing us a token.

Key is defined here: https://github.com/openstack/heat/blob/fee393755065ad6f19faa956181c3ccfb9b09871/heat/common/config.py#L100

    Allow attribute for deferred_auth_method

    We should switch to using deferred_auth_method=trusts by default,
    for the following reasons:
    - It's more secure, we won't have to store username/password anymore
    - It's better for users, because they won't have to provide a
    username/password anymore, e.g the box in horizon where we force
    them to enter a password even though horizon is already passing
    us a token.
