Tests refactor

[dann1]

• reworked bit the directory structure
  • master test file is called init.rb and will include examples from test libraries
  • added libraries with the examples on tests/lib
    • log.rb and crud.rb are example groups called within init.rb
    • more libraries will be added to verify more functionality described in Test Coverage #19
    • added template directory at tests/templates. These templates will be dynamically loaded when running tests as long as they are .json files starting with sr_.
• specifically use ubuntu 2204 runner for github actions
• Improved logs extraction on tests to load every file
• minor code changes
• Function service template now uses TTYLinux image on infra to speed up deployment time.
• Added Function-DaaS service-template to infra for complex template testing
