Better error logging for Delete action on /space endpoint

[jarifibrahim]

The DELETE action on /space endpoint often fails with could not delete space Example failure - https://errortracking.prod-preview.openshift.io/openshift_io/fabric8-wit/issues/2083 Error logs from Kibana shows

"error": "could not decode JSON formatted errors returned while deleting codebase ac20e514-d72a-46a2-bfc7-23ed58d762e9: invalid character '<' looking for beginning of value\n"

which doesn't show any information apart from the error.

This PR improves the error logging so that we can see what the actual response was from the codebase API when delete fails.
