refactor!: package integration testing framework

pyproject.toml file has been updated to correctly define the package structure

tests and testutils directories are now exposed as top-level packages named
integration_tests and integration_testutils respectively

sub-packages are now explicitly listed in pyproject.toml

docker-compose*.yml files have been moved from the project root into a new
tests/data/compose/ dir

docker-compose*.yml files are now treated as package data and included
in the integration_tests.data.compose package

import statements within the integration_tests and integration_testutils
directories have been updated

code that previously loaded docker-compose files using relative file paths
(e.g., in tests/conftest.py) has been refactored to use the compose files
trough importlib.resources

Ticket: QA-1170
Changelog: Refactored the integration testing suite into an actual, installable Python package named mender-integration
