[REF] bionic,focal: Add support for pysaml2 for server-auth/auth_saml2 module
python3-lasso doesn't have a pip package and it is raising "segmentation fault" error So, we need use another implementation for auth_saml2 for Odoo 12.0 (bionic) and 14.0 (focal)
There is a WIP PR in OCA using pysaml2:
It is working as expected without "segmentation fault" errors
The install documentation requires xmlsec1 apt package
