As extensions options has been deprecated, API sample tests
should run against all extension enable.
This commit enables all extensions for server PUT API tests and
remove its specific extensions tests and sample files.
Adding a hack for other tests which are still running with specific
extensions. That is needed to avoid all tests updates in single commit.
Partially implements blueprint api-sample-tests-with-all-extensions
