Don't always validate heat stack when adding parameters

There are certain cases we add parameters to plan environment
when creating and updating a plan. As part of that action we
aslo try to validate the stack/template. However, validation
would fail, if we've resource mappings in user-environment that
are not merged/added to the plan yet.

This adds new input flag to plan create and update workflows which
can then be changed in python-tripleoclient, so as not to imapct the
UI workflows.

Also includes I56258428d7a9461af64055a5605f3227bfadda2f that fixes
some issues with this patch on master.
