scheduler: ensure dup alloc names are fixed before plan submit. (#18873) (#18891) This change fixes a bug within the generic scheduler which meant duplicate alloc indexes (names) could be submitted to the plan applier and written to state. The bug originates from the placements calculation notion that names of allocations being replaced are blindly copied to their replacement. This is not correct in all cases, particularly when dealing with canaries. The fix updates the alloc name index tracker to include minor duplicate tracking. This can be used when computing placements to ensure duplicate are found, and a new name picked before the plan is submitted. The name index tracking is now passed from the reconciler to the generic scheduler via the results, so this does not have to be regenerated, or another data structure used.
