Refactor step_export and the driver interface to move the ovftool call
into the vmware driver. This refactor allows us to add meaningful tests
to step_export, which I have also added here.
* add progress tracker to vmware-esx iso upload. Add colored prefix to tracker to make it clear which build a tracker belongs to.
* fix mock; fix tests
* add kex algorithm option to ssh config
* regenerate code
* This commit fixes old vmware acceptance tests that have not been run in some time. It does this in two parts:
1) It modifies the minimal vmware build configuration to use a custom kex algorithm, which enables the ssh connection to succeed.
2) It modifies logic in reading and defaulting hardware config values, which was crashing.
3) It adds a new acceptance test with a preseed file to test loading from an http directory.
* Drop the iso_checksum_type & iso_checksum_url fields
In favor of simply using iso_checksum that will know what to do.
