Feat/devsu 2602 add observed variant annotations

[elewis2]

Adds table to store annotations (comment field plus json field similar to kbdata, to store table tags etc) on all variant types. Uses same pivot column as kb-matches table.

Updates rapid-report filtering to check for tags in the annotations field before doing other filtering, so that by updating the tag users can move variants to different rapid-report summary tables.
