Add ttp_parse helper function to codebase

[dmulyalin]

What this PR does

This PR developed as part of NANOG84 Hackathon efforts.

This PR add new helper function ttp_parse.

Motivation

Debugging and developing regular expressions can be tedious process, for some use cases it is possible to use TTP as a drop in to produce same results but with less efforts. Besides parsing, TTP also might bring other use cases like results data validation, formatting, testing or postprocessing.

How this was tested

Updated test/base/test_helpers.py file with test_ttp_parse test that does 5 sub-tests:

• check if raises TemplateRenderException when template does not exist
• check if raises TemplateRenderException for /utils/ttp_templates/bad_template.txt
• check if returns expected result as output for ./utils/ttp_templates/good_template.txt
• check if returns expected result as output for inline template
• check if returns expected result as output for template from ttp templates
