Working template get_function_url with test

[dave42w]

Description

This PR starts the process of implementing url_for so that Jinja templates can reference Robyn endpoints by function name rather than path see #996

Summary

[Updated] This PR adds a url_for that returns a fixed string and a test for this.
3rd Nov 24 Now looks up functions via the Robyn object router
7th Nov. All finished.

Changes are limited to 7 files (5 of them related to testing)

• templating.py (define the get_function_url function and add it to the global Jinja environment using generic add_function_to_globals())
• base_routes.py (call the set_robyn method of the JinjaTemplate)
• template.html (display test output of get_function_url with the sync_auth function
• test_get_requests.py (add an assert to check for /sync_auth in an href)
• test_get_function_url (unit tests)
• test_get_param_filled_url (unit tests)

I'm stuck. See #996 (comment)

Hi, @sansyrox

I think the test failures are CI timeouts, this has passed all the tests at some point since the last change.

Can we merge?

Hi @sansyrox
After the CI updates this is passing all tests. Can we merge it please.
Thanks
