Improve python tracing process

[tamarinvs19]

Description

Coverage

Supported new coverage measurement mode for python with uses instructions.
Current methods:

• use lines coverage (previous)
• use instructions coverage (by default now)

Added new option to change coverage output format:

• lines (default)
• instructions

Added new option to switch off sending coverage continuously during execution. If you use this option execution process will be faster but in case unexpected failure of execution we will lose coverage info. By default this option is inactive.

Modifications in utbot-framework

Make class Instruction open and inherited class PyInstruction. (See here)

All of this options you can set in python-cli:

• --coverage-measure-mode (LINES/INSTRUCTIONS)
• --do-not-send-coverage-continuously
• --coverage-output-format (LINES/INSTRUCTIONS)

Other

• Added progress bar for script run_tests.py
• Updated target values in test_configuration.json
• Used python instructions in python fuzzing

How to test

Automated tests

Run utbot-python/samples/run_tests_all.sh and check coverage results.

Manual tests

Run python-cli with new arguments

• I've set the proper labels for my PR (at least, for category and component).
• PR title and description are clear and intelligible.
• I've added enough comments to my code, particularly in hard-to-understand areas.
• The functionality I've repaired, changed or added is covered with automated tests.
• Manual tests have been provided optionally.
• The documentation for the functionality I've been working on is up-to-date.

Problems with conversion from PyInstruction to UtInstruction (and probably they shouldn't be different classes, this logic is too complex).
