Restructure MARC related events to have common and type specific ones

Purpose/Overview:

For the common events "BIB" part has to be removed. Additional events to support MARC Authority record flow has to be introduced. See the appropriate section of the spike for details.

Requirements/Scope:

1. Common MARC record events renamed
2. MARC Authority events added and used where apropriate

Acceptance criteria:

• existing flows for MARC Bib records work as before
• custom MARC Authority events issued at the appropriate time
• tests are added to validate the new events
