[AAP-48713] Alter authenticator maps to work with attribute expansion

[john-westcott-iv]

Description

• What is being changed?
  If you add the syntax {% for_attr_value(<attribute name>) %} to an authenticator map we will expand that value based on the values returned from an attribute on login.

• Why is this change needed?
  This will make gateway backwards compatible with an obscure SAML setting from AWX.

• How does this change address the issue?
  This allows authenticator maps to behave like the SAML authenticator can.

Doesn't really seem to change a lot long along the interface that matters with other systems, and fairly clear what this is doing and why it is needed.
