Asynchronously creates a new packet data bearer in the Modem.
This request may fail if the modem does not support additional bearers, if too many bearers are already defined, or if properties
are invalid.
See <link linkend="gdbus-method-org-freedesktop-ModemManager1-Modem.CreateBearer">CreateBearer</link> to check which properties may be passed.
When the operation is finished, callback will be invoked in the <link linkend="g-main-context-push-thread-default">
thread-default main loop</link> of the thread you are calling this method from. You can then call
create_bearer.end to get the result of the operation.
See create_bearer_sync for the synchronous, blocking version of this method.
