Copying Map

[madflojo]

Description

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change.

This change will create a copy of the task map and return it to users rather than returning the task map directly. Since maps in Go are essentially pointers, if a user is iterating over the returned map while it's being written to (scheduling, deleting, etc.) then there is a possibility of a race condition.

This change will prevent that by returning a copy of the map.
