Migrate modules to use self._query/self._request rather than commons.send_query()/commons.send_request()

[bsipocz]

Latter is more up to date with extra features (e.g. Sessions, caching, etc).
This affects several moduls:

• atomic Use self._request in all the modules #821
• besancon Use self._request in all the modules #821
• fermi Use self._request in all the modules #821
• gama Use self._request in all the modules #821
• hitran
• irsa Use self._request in all the modules #821
• irsa_dust Use self._request in all the modules #821
• magpis Use self._request in all the modules #821
• nasa_ads NASA ADS fix #602
• ned Use self._request in all the modules #821
• nist Use self._request in all the modules #821
• nrao NRAO votable: datatype specified incorrectly #629
• nvas Use self._request in all the modules #821
• ogle Use self._request in all the modules #821
• sdss Changing commons.send_request to self._request in sdss module #586
• simbad Use self._request in simbad module #822
• splatalogue Splatalogue: refactor to use cache #747
• template_module Use self._request in template module #819
• ukidss Use self._request in all the modules #821
• xmatch glade catalogue #751 (though the monkeypatch in the local tests still use it)

This is considered solved with #821 being merged as the only remaining module using commons.send_query is hitran and that needs a bigger refactoring first to use the common API, see #824
