If the user asks for a hostfile/hostlist inside of a managed allocation, make sure that rmaps filters these and maps processes based on them. Otherwise, it can result in inconsistent mappings across root and compute nodes if the user orders their hostfile differently than the resource manager.

For example: $. bsub -n 40 -m "node1 node2" mpirun -np 6 -host node1:2,node2:4 hostname would not map two hostname processes to node1 and four to node2. Instead, it would still think that each node1 and node2 had (for example) 20 cpu resources, and map accordingly. Signed-off-by: Austen Lauria <[email protected]> (cherry picked from commit 35cf87a)

Make a managed allocation filter a hostfile/hostlist.
If the user asks for a hostfile/hostlist inside of a managed allocation,
make sure that rmaps filters these and maps processes based on them. Otherwise,
it can result in inconsistent mappings across root and compute nodes if the
user orders their hostfile differently than the resource manager.

Fix bug where orte under a managed allocation does not honor -host.
For example:
$. bsub -n 40 -m "node1 node2" mpirun -np 6 -host node1:2,node2:4 hostname
would not map two hostname processes to node1 and four to node2.
Instead, it would still think that each node1
and node2 had (for example) 20 cpu resources, and map accordingly.
