magnum-tempest-plugin since commit[0] is using ast.literal_eval() to
parse the value set in [magnum].labels, so the formatting needs to be a
Python dict.
This is an example of how the string needs to look like to make the
parser happy:
>>> import ast
>>> ast.literal_eval('{"a": "1:1"}')
{'a': '1:1'}
