Ability to schedule all tests in series in same allocations #889
Description
When running a series that contains multiple tests that each run on a single node, each test is run in its own allocation. For things like whole-system runs of such a series, where each test needs to be run on each node of the system, it would be advantageous if the tests could run in the same allocation for each node, instead of separate ones for each node. This would help with scheduling the tests and getting the runs through the queue faster.
