As part of ongoing work to make the scheduler more legible and more robustly tested, we're implementing property testing of at least the reconciler. This changeset provides some infrastructure we'll need for generating the test cases using `pgregory.net/rapid`, without building out any of the property assertions yet (that'll be in upcoming PRs over the next couple weeks). The alloc reconciler generator produces a job, a previous version of the job, a set of tainted nodes, and a set of existing allocations. The node reconciler generator produces a job, a set of nodes, and allocations on those nodes. Reconnecting allocs are not yet well-covered by these generators, and with ~40 dimensions covered so far we may need to pull those out to their own tests in order to get good coverage. Note the scenarios only randomize fields of interest; fields like the job name that don't impact the reconciler would use up available shrink cycles on failed tests without actually reducing the scope of the scenario.
