Dag Wieers e152b277cf Use locking for concurrent file access (#52567)
* Use locking for concurrent file access

This implements locking to be used for modules that are used for
concurrent file access, like lineinfile or known_hosts.

* Reinstate lock_timeout

This commit includes:
- New file locking infrastructure for modules
- Enable timeout tests
- Madifications to support concurrency with lineinfile

* Rebase, update changelog and tests

We need to specify ansible_python_interpreter to avoid running interpreter discovery and selecting the incorrect interpreter.

Remove the import of lock in known_hosts since it is not used.
