Since the host_guid is unique to the printer, it is more reliable for
identifying the cloud printers. This comes in handy when the cloud
printer is removed from the account and re-added. With the host_guid,
the printer that is added again can be properly identified as an
existing Cura cloud printer, and be linked to the original. To
achieve that, the META_CLUSTER_ID of the printer is updated with the
new one that is generated when the printer is added again to the
account.

This has to be done in order to avoid weird actions taking place, such
as the user pressing to remove the printers while another sync is
happening.

After 30 seconds a new sync will be initiated, which will alter the
conents of self.reported_device_ids, thus making the current message
deprecated. Therefore, it is best to have a maximum lifetime of 30
seconds.

When the "Printers removed from account" message pops up, it will give
the option to the user to remove all the printers that are not linked
to his/her account from Cura. Since this action removes all
configurations, it first pops a confirmation question box, and if the
user insists, these printers are purged from Cura.
Note: In order to properly delete all the files, the printers have to
be activated first before they are removed, or else some extruder
files in %appdata%/cura/<version>/user and %appdata%/cura/<version>/
extruders remain.

Previously the print job was sent with multiple PUT requests. This was necessary since the request was made with the Python Requests library, which freezes the interface while it's running. By breaking the upload up in chunks, it would at least periodically keep updating the interface (4 times per second or so, depending on your internet speed and Ultimaker's). Later on, this was replaced by a QNetworkRequest which doesn't freeze the interface in a refactor, but it was still broken up in chunks.
Recently that was again refactored to use Uranium's HttpRequestManager, which under the covers also uses QNetworkRequest. This also doesn't freeze while uploading, which is good. However for some reason the second chunk would always give a QNetworkReply::ProtocolUnknownError, which is a bit of a catch-all error for any HTTP status codes not supported by Qt. I was not able to figure out what was really going wrong there, but it has something to do with the content-range header and making multiple requests.
Instead of fixing that, I've removed the chunking. This simplifies the code a lot and doesn't have any implications for the user, since it still doesn't freeze the interface while the network request is ongoing. It should be slightly faster to upload, and reduce load on the server too.
However the disadvantage is that the original bug is probably still there if it was a bug in the HttpRequestManager. If it was a bug in the ToolPathUploader I probably deleted the bug here.

their purpose.

The meta data entry was rename to be more representative of its
function. In addition, the bool metadata entry is now properly
handled using the parseBool function.

When a cloud printer is no longer received from mycloud, it is safe to
assume that the printer is removed from the account. In such a case,
the new function _devicesRemovedFromAccount(..) will retrieve all the
devices that are to be removed (i.e. they are added in Cura but they
do not exist in the clusters received from mycloud) and will remove
their output device. In addition the function will generate a message
that mentions all the devices that were no longer linked to the
account.
In order to achieve that, the Cloud/CloudOutputDeviceManager is
enriched with the dictionary self._um_cloud_printers that contains all
the currently existing cloud-enabled devices that were previously added
in Cura. In addition, the meta-data field "removed_from_account" is
added to all the cloud-enabled Cura devices to distinguish the ones
actually linked to the current account.
With these additions, the cloud devices that are removed from the
account will be automagically re-linked to it once the devices are once
again retrieved from mycloud for the specific account.

These two version upgraders do the same operation. Their code is copied. Instead, we can just let one version upgrader upgrade both versions of the files.

This makes the cluster size also available when the machine is offline.
Also fixes an issue where the cluster size is improperly restored
once the internet connection comes back online, resulting in the printer
showing as a single printer until next sync
