LP#1786552: optionally restrict auth_proxy login by home OU

This adds a new restrict_by_home_ou setting to auth_proxy authenticator
config.  When enabled, if the login request includes an org param, the
authenticator will refuse to authenticate a user unless their home OU
matches or is a descendant of that org; login fails and auth_proxy
proceeds to the next configured authenticator.
