Add strip_flags

Copybara Import from #324

BEGIN_PUBLIC
Add strip_flags (#324)

Previously the strip action appeared to be entirely invalid since no
flags were passed to strip. I believe this is because the strip action
was configured in the legacy feature code without any extra features,
just directly on the action.

Closes #324
