Allow SSH connection callers to not permit agent usage

While debugging the ``rescue`` test functionality with ironic's
tempest plugin, we discovered that if the environment suggests the
agent is available, then we may enter a situation where the test
can fail because paramiko prefers ssh over password authentication.

This is important, because for rescue functionality in particular,
it is password authentication based without the use of SSH keys,
as a temporary password is generated by the services and provided
to the user requesting to rescue the instance/node.

Instead of trying to make an assumption that password being present
means we should just disable the agent, explicitly allow the caller
to specify it.
