[Python-modules-team] Bug#948397: python-softlayer: Update to prompt-toolkit 2 compatible version

[Gordon Ball]

Source: python-softlayer
Severity: serious
Justification: Policy 7.4
Control: blocks 944227 -1

Dear Maintainer,

prompt-toolkit has been updated to the 2.x series. The current version
of python-softlayer requires prompt-toolkit 1, and was added to the
Breaks: list for prompt-toolkit 2.0.10.

This should be resolvable by updating to softlayer 5.8 or later. ScottK
responded to the original prompt-toolkit upgrade bug (#914698), but it
appears he's no longer listed as an uploader for this package.
