Auth Dbo: Consider adding schema support for UserDatabase
Wt Dbo provides good support for schema-qualified tables and it might be helpful in some use cases to place Auth Dbo tables in a separate schema.
However, the current Wt github (3.3.3-19-gad17d0b) does not quote all schema references and this results in "relation ... does not exist" errors with Postgresql.
The first attached patch adds support for schema qualified tables. It has been lightly tested with Postgres. The patch has a dependency on the tableNameQuoted method provided in patch with issue #3616, and serves as a sample use case. As a note, the auth_token table will include a column name of the form "user_schema.auth_info_id". This works, as it is quoted by Dbo and is a valid Postgres column name, but it might be unexpected.
A second attached patch provides some rudimentary database tests of Auth Dbo, both with and without schemas.
