Subject: [PATCH] templates: move the globals up to the Environment
 (Jinja2 3.0.0) (#419)

* jinja: fix TemplateNotFound missing name

The TemplateNotFound exception requires a parameter, name, that is
missing in one of the calls.

File "/usr/lib/python3.8/site-packages/salt/utils/jinja.py", line 158, in get_source
    raise TemplateNotFound
TypeError: __init__() missing 1 required positional argument: 'name'

This patch add the missing parameter in the raise call.

* templates: move the globals up to the Environment

When creating a Jinja2 environment, we populate the globals in the
Template object that we generate from the environment.  This cause a
problem when there is a {% include "./file.sls" %} in the template, as
cannot find in the environment globals information like the "tpldir",
for example, making the relative path to be unresolved.

Seems that in Jinja2 2.X this behaviour is not present, so attaching the
globals to the Template will make the include to work, but since Jinja2
3.0.0 this is not the case.  Maybe related with the re-architecture from
https://github.com/pallets/jinja/issues/295

This patch populate the globals in the Environment level, making this
and other variables reachable by the Jinja templates.

Fix #55159
