OIDC - Multiple connected accounts for one user [probably via new connected_account db table] #787
Description
Save multiple oidc ids, oidc emails, oidc usernames and other oidc-related profile data for one user
e.g. by creating new connected_account table that allows storing the connected account profile data for user_id and provider.
This should also support multiple oidc providers.
provider column should contain string that makes it easy to distinguish:
- internal google, microsoft, github providers
- oidc provider with different methods as in OIDC_ENABLED_METHODS defined by user
- multiple oidc providers (via name) - not supported yet (OIDC - Multiple generic OIDCs setup #788)
