[TASK] Remove Tika Server BE Module

[dkd-kaehm]

The Solr Server Module is still experimental and does not work properly.
Therefore it should be discussed if the module should be upgraded/tuned up or removed.

Current issues:

• By trying starting Tika server via BE Module no checks are done about jar file existence and other things like restart & co..
• It does not start the daemon properly. It tries to start the server and makes the sys_registry entry independently of the result, it assumes simply putative Process-ID(PID) without checks about the existence of this process(for example after system restart the pid is still in TYPO3 registry, and so on), which results in fatals and exceptions by calls to this module and sometimes to whole TYPO3 Backend.

IMHO this module makes more troubles as advantage on all possible scenarios.

---

The devOps world and TYPO3 projects have been changed since implementation time of this module.
Nobody wants to start daemons via PHP/TYPO3 today.
