* make it work even for drafts that have been published before
* also extract a few pieces into utility functions

* because reindexing has been implemented in the core modules for a long
  time now

* we never used it anyway

* because we moved away from setuptools which had wrappers

* in hopes that publish failures will be less confusing from now on
* also, to detect errors (e.g. missing files in MANIFEST.in) earlier

* concentrate the configuration of all calls in one place

* because the 'rdm-records rebuild-index' command doesn't rebuild
  indices for all available/required services (at the moment)
