MDL-41421 tool_generator: Refactoring make_form to make_course_form

Also:
- Added a soft password for the
newly generated users so we can use
them to log in the site when running
performance tests.
- Added a method to see the courses-users
relation from outside course_backend class.
MDL-41421 tool_generator: Import .jmx template

Ideally we should generate all the XML based on
modular components so we can also switch templates
between different sizes, this is a first step and
more work should be done in future in this direction.
MDL-41421 tool_generator: Adding a test plan generator to feed JMeter

Also changing course_backend.php coding style
according to codechecker.
MDL-41421 tool_generator: Adding a CLI tool to generate the test plan
MDL-41421 tool_generator: Using default values in the test plan

Using optional properties allows us to only set the default
value, so if nothing else is specified when running jmeter the
default value will be used as it is being used now. Also requires
modification in moodle-performance-comparison to forward the arguments
to jmeter.
