<description>
The least amount of time(msec.) an inactive (decommissioned or shutdown) node can
stay in the nodes list of the resourcemanager after being declared untracked.
A node is marked untracked if and only if it is absent from both include and
exclude nodemanager lists on the RM. All inactive nodes are checked twice per
timeout interval or every 10 minutes, whichever is lesser, and marked appropriately.
The same is done when refreshNodes command (graceful or otherwise) is invoked.
