* this is useful to see if the authentication and everything else works

* this is useful for local/development instances that have self-signed
  certificates and thus wouldn't pass the SSL check

* because they're ancient, and InvenioRDM has started providing version
  upgrade guides themselves since v1

* add script for fetching logs from the log server (OS)
* add golang-based program for calculating statistics from logs
* add README with more detailed information

* display the last parsed timestamp before the results, in addition to
  the start timestamp
* also fix the wrong timestamp being displayed as start date

* apparently, the file content would sometimes not be sent otherwise

* previously, the connection object could time out and cause issues
* also, include the error type in the message

* offers improved error handling
* should be more portable w.r.t. the execution environment

* add support for authentication tokens (required by InvenioRDM 1.0+)
* add switch to not publish created records

* instead, add a script that does a metadata migration between two
  concrete versions of InvenioRDM
* note: it's not guaranteed that the naming w.r.t. the original version
  is accurate... could also have been the january metadata model

* also, actually pass the file names to 'invenio tuw records update ...'

* this prevents the marshmallow schema from transforming the records in
  any way that we wouldn't want (e.g. hiding fields)

InvenioRDM (November Release) runs into errors when the resource_type
