add flag.Parse so HandlFlags works correctly (#14214)

* add flag.Parse so HandlFlags works correctly

* fix: move flag init outside package initialization

Since go 1.13 testing flags are now only registered when running
a test binary, and packages that call flag.Parse during package
initialization may cause tests to fail.

To resolve this move the flag init to a proper function outside of
package init and call it explicitly
