When uploading box file, check if the size is greater than
5GB. If the size is larger and the direct to storage option
is enabled, disable the option due to current 5GB restriction
on direct uploads.
This PR is dependent on the 2.1.0 release of the vagrant_cloud
library. It updates the `cloud` command to use the new interface
for interacting with the Vagrant Cloud API. It also adds support
for direct to backend storage uploads, and defaults to this
method.
Also included is a bit of cleanup refactoring, addition of method
documentation, and fixing up some small issues around custom username
usage within the internal client for authentication.
Prior to this commit, if a user didn't supply a box file on disk or a
box url, Vagrant would crash and display a stacktrace with an invalid
file. This commit fixes that by adding some extra handling around the
arguments supplied to the publish command.
Prior to this commit, Vagrant would attempt to path expand a file that
didn't exist if it was left out of the passed in arguments and no
`--url` was used for external box uploading. This commit fixes that by
adding some additional validation for the passed in box file.
This commit introduces a new uploader class for uploading files and
splits up some commonly used functionality between it and the downloader
class into a curl helper library.
