Refactor automation orchestrator to support branching (#14461) 

* refactor automation thread

* fix infinite loop in branching

* remove try catch

* remove spacing

* remove unecessary addition of branch outputs

* pr comments

* remove loopstep instance variable

* add test to cover failure scenario

* add tests for other automationf ailure conditions

* update test name

* use private keyword instead of underscore

* parse int / string safely

* fix refs

* add condition support for branching and tests

* create helper function for recursing all search filters

* move helper func

* fix import
