not sure the spack_setup_clingo logic works

[cyrush]

for skipping clingo here:

https://github.com/LLNL/uberenv/blob/7199133a517cfece51f47c102d9dab85b8a6aa4c/uberenv.py#L907

I don't see how this can work:

'spack_setup_clingo': 'false'

The json contents are not parsed to an actual boolean -- the result is a string.

it wouldn't work if set to string "false", but if you set it to a boolean value false, it will be converted to a python boolean False https://docs.python.org/3/library/json.html#json-to-py-table

'spack_setup_clingo': false
