Make compute-trust.json compatible with TrustFilter
Make compute-trust.json compatible with TrustFilter

Current properties inside compute-trust.json does not match
with how TrustFilter in nova works. JSON provides True/False
boolean values but TrustFilter expects trusted/untrusted/unknown
string values. This patch repairs compute-trust.json to be
compatible with TrustFilter.
