TaskRouter now supports Activity evaluation with Worker-List API

TaskRouter now supports the evaluation of Activity name and SID in Worker expressions for the Worker-list API.

For example, developers can use this to fetch workers in different activities
using GET /Workers?TargetWorkersExpression=activity_name in ['ABC',
'XYZ'] or to fetch workers using a partial name match using GET /Workers?TargetWorkersExpression=activity_name contains 'MNO'.

For more detailed information please refer to the expression syntax documentation and the Worker Resource documentation.
