Function for changing the data source of a dashboard

[vvaezian]

For the first version we can assume the source of all the cards on the dashboard are the same (an initial check needs to be done in this case).
The function for changing the data source of a card is used for each card of the dashboard.
The dashboard filters needs to be updated as well.

Hi!
Thank you for this feature (all the work you put in this fantastic lib)
if you need a hand I would be glad to help

Glad that it has been helpful.
I'll work on new features whenever I get time.
BTW changing the data source of a card has been implemented using the clone_card function. The function for changing data source of a dashboard (the current issue) will build on top of that.
