Provide the option for on-demand instance vs spot instance

[br-sn]

For some very large cracking jobs, on-demand becomes necessary to avoid having the instance interrupted. Provide an option to choose more expensive on-demand instances rather than spot instances for jobs that require it.

I would appreciate the option as a feature request. We are constantly getting booted and having the ability to resume the cracking or go to a more expensive on-demand instance woudl be preferable.

I'm working on a new orchestration engine that will open the door for more ethereal compute options, including across other clouds. It's going to take some time, but I hope to have more options down the road.
