Configurable unit tests setup

[pboychev-bcom]

Description

Current state:

• The solution can only work with Jasmine.
• There is no OOTB way to upgrade the used Jasmine version.

Desired state:

• The user should be able to choose which unit tests framework to use - e.g. Jasmine / Jest / another.
• The tool should enable the user to configure the tests in more depth, providing guidance for the configuration.
• The tool should generate a set "default" unit tests configuration based on the tests setup if there isn't any; this configuration can then be fine-tuned by the user to their needs, e.g. tweaking the configuration in the framework config file, that way the tool will create a base for the tests and the user can control the tests setup and configuration, upgrade packages etc.
• By default the latest versions of the frameworks should be used for generating the default tests configuration, ensuring latest and greatest features. Upgrade should be done by changing the generated configuration files.
• Backward compatibility should be ensured as the tool uses Jasmine with the current behaviour if there is no configuration provided.
