Subject: [PATCH] [ML] Stop reading the ml.max_open_jobs node attribute
 (#115524) (#115580)

The ml.max_open_jobs node attribute is going away in
version 8, as the maximum number of open jobs has been
defined by a dynamic cluster-wide setting during the 7
series and there is no chance of version 8 needing to
run in a mixed version cluster with version 6.

The ml.machine_memory attribute will still be available,
so this can be checked instead as a way of detecting ML
nodes.
