[FEATURE] enable automations and queries to use loops during templating / CSCLSROZ-214

[JoernBerkefeld]

idea is to use mustache or handlebars.js logic to create multiple combined queries if needed (UNION ALL) based on the markets defined per BU in a marketlist.

 

similarly, use the ANNOTATION field on automations to link multiple queries (or other activities) instead of just hte one found in dev

 

--> required if PROD has multiple country BUs that are all defined by one DEV bu
