Upgrade Notices

When sso.saml.metadata is set in the umbrella values, the Anchore configure-sso job will use the provided XML directly for IdP metadata configuration instead of fetching it from the IdP metadata URL. If sso.saml.metadata is not set, the existing behavior of fetching metadata from the URL at deploy time is unchanged.
