BUG/MAJOR: ssl/ocsp: crash with ocsp when old process exit or using ocsp CLI

This patch reverts 2 fixes that were made in an attempt to fix the
ocsp-update feature used with the 'commit ssl cert' command.

The patches crash the worker when doing a soft-stop when the 'set ssl
ocsp-response' command was used, or during runtime if the ocsp-update
was used.

This was reported in issue #2462 and #2442.

The last patch reverted is the associated reg-test.

Revert "BUG/MEDIUM: ssl: Fix crash when calling "update ssl ocsp-response" when an update is ongoing"
This reverts commit 5e66bf26ec.

Revert "BUG/MEDIUM: ocsp: Separate refcount per instance and per store"
This reverts commit 04b77f84d1b52185fc64735d7d81137479d68b00.

Revert "REGTESTS: ssl: Add OCSP related tests"
This reverts commit acd1b85d3442fc58164bd0fb96e72f3d4b501d15.
