When possible record the name of the user that requested the
job. The klippy_api's component now takes an optional user
argument in its "start_print" method. This user is broadcast
in an event after a print request successfully returns.

The default behavior of the subscribe API shares all subscription
requests. API Transports require their own subscription. Add
a method to facilitate this request.

This change refactors the APIDefiniton into a dataclass, allowing
defs to be shared directly among HTTP and RPC requests. In
addition, all transports now share one instance of JSONRPC,
removing duplicate registration. API Defintiions are registered
with the RPC Dispatcher, and it validates the Transport type.
In addition tranports may perform their own validation prior
to request execution.

This callback will only fire after a component has requested
a subscription, preventing early updates while the component
is waiting for the subscription request to complete. It is still
valid for components to register the "server:status_update"
event handler if this behavior is not a concern.

Handle a race condition where a shutdown event could be received
from the webhooks subscription during initialization.

The "wait_connected" method would block indefinitely until a klippy
connection is established. This isn't the behavior we want, we only
want to wait "if" a connection has been established until Klippy
reports that its startup sequence is complete.

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()`.

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.

Rather than add these arguments to the config, use a method to access them from the server object.

This resolves a potential issue where clients could anticipate that all items in the status parameter are objects.

This switches Moonraker from calling `CANCEL_PRINT` and alikes
to rather use `pause_resume/` API that underneath calls
the relevant G-Codes.
This done, this way, allows Klipper to be able to interrupt
blocking operations gracefully.
