Entity.columns class property replaced by Entity.get_columns method. 
Again, Python < 3.9 doesn't like the combination of `@property` +
`@classmethod`.

_variable should be an external global function rather than a class property. 
The combination of `@property` + `@classmethod` isn't supported on
Python < 3.9.

Fixed parenthesised multi-with statement. 
This syntax is not supported on Python < 3.9, and therefore it should be
broken down as a multi-line statement.

Sync the latest parse timestamps in main instead of __init__ in rss. 
We should load the latest timestamps from the db when the thread starts
instead of doing it in the constructor.

The constructor may be invoked when the entities engine hasn't been
initialized yet, and result in deadlocks.

Added @ensure_initialized decorator to actions in variable. 
The `variable` plugin may break in the constructor the first time the
application is started.

That's because it tries to initialize the cache of stored variables, but
the local database hasn't yet been initialized.

That's because plugins are registered _before_ the entities engine is
initialized, as the entities engine assumes that it already has plugins
to scan for entities.

Therefore, the initialization of the `variable` plugin's cache should be
lazy (only done upon the first call to `get`/`set` etc.), in order to
prevent deadlock situations where the plugin waits for the engine to
start, but the engine will be initialized only after the plugin is
ready.

And the lazy initialization logic should also ensure that the entities
engine has been properly started (and emit a `TimeoutError` if that's
not the case), in order to prevent race conditions.

Ignore Redis errors when a backend sends an unregister notify event. 
When that happens, it's most likely that the application is already
stopping and the Redis service has already been terminated.

The __main__ function should take no arguments. 
setup.py won't pass any arguments to `main()`, so the default entry
point should get them itself from `sys.argv`.

Extended manifest files with Python system packages (if available). 
- If a Python optional dependency is available as a system package on
  the target system, try and install it that route rather than pip. It's
  usually faster and it decreases the risk of breaking system packages.

- Added support for apk dependencies in manifest files. This brings the
  number of distros officially supported by all the extensions to four:

  - Alpine
  - Arch
  - Debian
  - Ubuntu

Implemented HttpBackend._stop_workers. 
The Tornado WSGI container won't guarantee the termination of the
spawned workers upon termination, so the code of the backend has to take
care of it and terminate all the children processes of the server
process when it terminates.

This also means that `psutil` is now a required base dependency, as we
need to expand the process subtree under the webserver launcher.
