blank return strings from processing scripts cause json parse error

[Adam Stokes]

[Impact]
This will break any post processing script attempting to retry a invalid JSON string.

[Test Case]
Simply running `conjure-up openstack` through to the end will show this error.

[Regression Potential]
This should be minimal as we add additional exception handling to gracefully deal with these errors.

[Additional Info]
During parsing of results from post processing scripts that return a JSON dictionary and error would occur if that JSON response was not properly formatted or an empty string.

Please upload the fix to yakkety, or if it already is fixed in 2.0 please close the floating task. Otherwise this can't progress into xenial-updates.
