[IMP] email_template: add `datetime` and `dateutil.relativedelta` in the global rendering context for templates 

The `dateutil` package is not included directly in the globals because
`dateutil.relativedelta.relativedelta` is an old-style class and jinja2
does not appear to support instantiating old-style classes within an
expression, so `relativedelta` support is provided using a "lambda proxy".
