[BUG] Jinja variable 'salt.utils.templates.AliasedLoader object' has no attribute 'boto_ssm'

Description
I would like to get params from AWS ssm instead of pillar. During state.highstate I'm getting the following error:

salt.exceptions.SaltRenderError: Jinja variable 'salt.utils.templates.AliasedLoader object' has no attribute 'boto_ssm'
c:\salt\var\cache\salt\minion\files\base\tag-dm-worker-common-win-py3/files/worker.conf(1):
---
{%- set rmq_hosts = salt['boto_ssm'].get_parameter('/tag/rabbitmq/'+ grains['env_name'] +'/amqp_url_list').split('\n') -%}    <======================

Setup
WIndows 2012 R2 Standard.
Jinja template looks like this:

{%- set rmq_hosts = salt['boto_ssm'].get_parameter('/tag/rabbitmq/'+ grains['env_name'] +'/amqp_url_list').split('\n') -%}

Steps to Reproduce the behavior
Install salt-minion on Windows, execute state.highstate for this salt-minion.

Expected behavior
Jinja template rendered without errors

Additional context
On Linux I was able to solve it with installing both boto3 and boto, but on Windows installing boto3 breaks salt-minion as it replaces urllib3 with version 1.26.x, however salt-minion wants urllib3==1.24.3 and refuses to start.

Start with the Jinja call to salt['boto_ssm'].get_parameter and the Salt minion dependency setup on Windows. Reproduce state.highstate with the reported Salt 3002.2 environment, then trace why boto_ssm is unavailable and how boto3's urllib3 conflict affects startup. Done means the template renders successfully on Windows with supported dependencies.
