Summary:
The config 'histeditng' was removed in upstream recently and is
therefore, no longer required. This commit removes the config and fixes some
tests which were dependent on it.
Test Plan: Ran all the tests.

Summary:
--retry can be used instead of --continue when histedit failed on "exec" (due to it returning a non-zero exit code) and the user wants to repeate that command rather than continuing past it
--show-plan will print the remaining plan of histedit during an interrupted histedit
Test Plan: cd fb-hgext/tests/ && rt
