Always use "--" in "dom parse" when document is interpolated
This is a safety measure to make sure that the document parsed is never confused with an option, when the document starts with a "-". In the best case, the error message provided by "dom parse" might be misleading. This might be a problem for user contributed documents (passed as variables, or return values from functions).
The double dash is supported in tdom since version 0.9.0.
Fixes for regression test: util_http_json_encoding
This change corrects 2 bugs, causing the regression test to fail under certain circumstances: 1) use for test location [::acs::test::url] instead of [ad_url] The call [::acs::test::url] should be used for all tests in the regression tests and avoids problems with wrong URLs when running e.g. in a container 2) When running on a setup with self-signed certificates, the curl requests require a "-k" flag to be passed. Otherwise, the regression test fails.
