Remove invenio imports

[jalavik]

At the bottom you can see the current output of invenio imports in harvesting-kit. If we get rid of these, we can finally add travis testing and have our pull-requests automatically checked etc.

Looking at the list, most things are easy to fix, such as config variables and exception handling.

• [x] replace all invenio.config imports with our config equivalents or just mkstemp locations
• [x] backport filedownloadutils.download_url to harvestingkit
• [x] remove all register_exception calls as it is only for Invenio (clients should instead call this)
• [ ] move calls to task_low_level_submission to clients instead
• [x] move calls to extract_references_from_string_xml to clients instead (or pass callback func)
• [x] move calls to get_kbs to clients instead
• [ ] remove dependency on BibRecDocs
• [x] find an alternative to run_shell_command
