Fixes #6101 - lfenv conditional resolv prior

lifecycle-environment command update/create should only conditionaly
resolve for prior if option is given.
Fixes #6105 - subs refresh_hist & delete-manifest

subscription refresh-history and delete-manifest commands were
requesting subscription id when subscription id should not need to be
provided. Fix was to use Command rather than a SingleResourceCommand.
