Changes in this PR

1. taskToDomain map is sent as a part of the event payload.
2. If no taskToDomain is mentioned in the event handler definition then a new workflow will be triggered with the parent tasktoDomain map.
3. Payload taskToDomain will be overwritten by the taskToDomain map coded as part of the event handler definition

Describe the new behavior from this PR, and why it's needed
Whenever an event is fired to trigger a workflow, the taskToDomain map of the parent workflow is not passed as a part of the event payload which leads to triggered child workflow not run in isolation. The only way to run the child workflow in isolation is not hard code the taskToDomain map in event handler definition.
This PR introduce then change where taskToDomain map is passed as part of event payload and if event handler definition does not have the taskToDomain map then the parent taskToDomain map is applied to child workflow. Similar change is already in place with subworkflows
Payload taskToDomain will be overwritten by the taskToDomain map coded as part of event handler definition.
