[Koha] Saying farewell to QueryParser

[Renvoize, Martin]

Hi All,

As discussed at the development meeting on the 19th February
<https://meetings.koha-community.org/2020/development_irc_meeting_19_february_2020.2020-02-19-14.02.html>
we have decided to remove the QueryParser option and code from Koha.

This decision was not taken lightly, but with the move towards
Elasticsearch and the lack of follow-through support for continued bug
fixing and improvements in the QueryParser code we decided to reduce out
maintenance debt and remove it.  We used HEA to try to ascertain if anyone
had been using the option and it appears to have little to zero adoption
(and at the time of writing, had a number of bad bugs which meant using it
was advised against for some time).

Jonathan D has worked hard to produce a patch quickly to do this work and I
intend to push this later today to reduce the risk of repetitive rebase
requirements.

So, join me in saying farewell to QueryParser, a nice idea never fully
realised.

Many thanks as ever to the koha development team,
