* feat: error on unsupported compose features
This implements a check for the unimplemented features of the uncloud
support matrix and points to the matrix in the error.
Fixes: #237
This redos #277, as I messed up my branch, (basically rebase gone
wrong).

* Fix tests by capturing stderr
The error should be nil, but we _do_ want to know if the user saw an
warning. Redirect stderr to capture this as the error is emited by
printing to stderr.
