Add SAML SSO configuration for Twistlock

Package Merge Request

Package Changes

Update the Twistlock init script to configure SAML SSO. Adding the twistlock-sso.sh script after twistlock-license.sh, so that we can automate the creation of additionalUsers using the SAML role. Focused on SAML rather than the other protocols since this is the one we got working with P1 Keycloak as compared to OIDC.
