Make it context aware

[6543]

It would be nice to have the option to pass an context into it, witch if canceled either rollback or stop at the next posible position.

In the best case the migrations itselve can decide what to do on context cancel like if it's a bulck migration of data, it stops after a bulck was done and if you restart the migration it starts where it ended. or if it's something atomic either rolback or finish ... and then end

else if context is not canceled we just progress as it is done now

This sounds reasonable, and enough of a benefit that it would be a good reason to even be a breaking change (with the release of a v2).

Downstreams would have to be notified if this change is made (ping @kolaente)

Sounds good to me 👍
