Sets a cluster wide upgrade_mode setting that prepares machine learning
indices for an upgrade.
When upgrading your cluster, in some circumstances you must restart your
nodes and reindex your machine learning indices. In those circumstances,
there must be no machine learning jobs running. You can close the machine
learning jobs, do the upgrade, then open all the jobs again. Alternatively,
you can use this API to temporarily halt tasks associated with the jobs and
datafeeds and prevent new jobs from opening. You can also use this API
during upgrades that do not require you to reindex your machine learning
indices, though stopping jobs is not a requirement in that case.
You can see the current value for the upgrade_mode setting by using the get
machine learning info API.
