Allow escaping a dollar sign when expanding external labels (#10129) * Allow escaping a dollar sign when expanding external labels There is currently no mechanism to natively escape a dollar sign in the os.Expand function. As a workaround, this commit modifies the external label expansion logic to treat a double dollar ($$) as a mechanism for escaping the dollar character.
