Moonraker depends on "future" annotations and uses fstrings, so
versions of Python older than 3.7 will fail to load and never make
it to the version check.

Start tracking the Remote API version separately from the application
version. This allows the API to stick to semantic versioning while
and track the application version separately. This is necessary as
we prepare to release a beta.

Moonraker requires that some Klipper objects be configured
and loaded. This check has always been performed and logged,
now track and report missing requirements.

Move the KlippyConnection class into its own module. Refactor
init to use loops rather than callbacks, this reduces complexity
of tracking and cancelling callback handles.
All Klippy state previously tracked by the Server is now in the
KlippyConnection. This improves testing and makes the code
less ambiguous, ie: the `server.make_request()` method is not
as clear as `klippy.request()`.

Move the version check to the top of the module. An older version
of python is unlikely to make it beyond the initial import statements,
so print a message to stdout and stderr.
Move argument parsing out of the main method. This makes it possible
to invoke main without parsing command line arguments, which is useful
for tests.

Rather than instantiate a new version of the event loop wrapper
we can simply reset the internal event loop.

Don't load components and start the server from within the
__init__() method. Break those out and call them in __main__().
This makes unit testing individual components possible.

Attempt to take a backup of the configuration file if Moonraker
loads successfully and has not seen a config change.
If Moonraker fails to load due to a config error, attempt to fallback
to the backup configuration. If that fails, exit the server.

Don't exit the server if the log path is invalid. Instead start
logging to stdout and add a warning for the user to

Allow base modules to register themselves as components during
initialization. This makes them accessible via lookup_component()

Move logging setup to the Server class and enable asyncio debugging.
Sanitize debug logging for all "/access" endpoints so tokens and

Occasionally a server restart will fail as the new loop instantiates as closed. This seems to be an issue with asyncio, attempt to work around by retyring to create a new loop.

Previously a set was used to remove duplicate components, however this is unnecessary as the `load_component` method immediately returns dups. Using a list should preserve the load order based on the configuration, making it more predictable.

The `send_event()` method now returns a future that can be awaited until all callbacks are complete. All events emitted during Klipper init are now awaited, and a Lock is used to prevent re-entry. This resolves potential timing issues with commands sent during the init sequence.

Components may call a "component_init" method for initialization that requires async calls. This allows moonraker to track init progress and guarantee init order.
