python-configshell-fb: 1.1.fb12
python-rtslib-fb: 2.1.fb47
targetcli-fb: 2.1.fb35

This depends on python-rtslib-fb>=2.1.fb47 now.

It might not be absolutely necessary to depend on version >= 1.1.fb12 of
python-configshell-fb, but I added it since that version
introduces raising ExecutionError for the caller
and targetcli handles these now.
The ExecutionError class was provided since the first release though.
