Currently the Dogtag RestClient '_ssldo' method requires a session
cookie unconditionally, however, not all REST methods require a
session: some do not require authentication at all, and some will
authenticate the agent on the fly.
To avoid unnecessary login/logout requests via the context manager,
add the 'use_session' keyword argument to '_ssldo'. It defaults to
'True' to preserve existing behaviour (session required) but a
caller can set to 'False' to avoid the requirement.
