Add a requestMemoryMax config in ctrl_bps

Description

It would be useful to be able to specify a maximum memory request in addition to a memoryMultiplier. For example, for lsst-devl the maximum memory available to nodes is 125GB, so for a memory-intensive job, these settings:

requestMemory: 32000
requestMemoryMax: 120000
memoryMultiplier: 2.0

... would increase the memory request from 32000 to 64000 and then 120000 (rather than 128000) on exceeding the previous limit.

If the maximum request is exceeded, I would be satisfied with the default being to kill the job; some users might prefer for it to remain held.
