[16.0][IMP][auth_saml] Res.users autoprovisioning feature on login

[arnaudlayec]

This commit add the possibility for Odoo administrator to specify a list of trusted "domains*" per SAML providers. When a user tries to authenticate to Odoo using SAML, coming from such domain* & providers, its Odoo res.users account is automatically created (copied from base.default_user) instead of showing him/her 'Permission denied' or 'No access granted to this database'. *domain refers to the suffix or login used for SAML authentication, like : [email protected], like from Google, Microsoft, ...

Thus, it removes for Odoo administrators who choose SAML authentication the tasks to pre-create all users manually or through SCIM connectors. However, it does not remove the need to tailor users access rights after the 1st login of the user.
