allow to customize bind mounts for TERR/Python/R service engine container

Customer wants to read / write files on host OS or NAS shared folder from TERR/Python/R data functions when TERR/Python/R service is configured to use container for engine process.

So to do this we need to add more bind mounts to the container.

aka equivilent capability to the --volume option

https://docs.docker.com/engine/storage/bind-mounts/

docker run -v <host-path>:<container-path>[:opts]

Currently I suggest them to use below bind mount to achive this but it's not a very appropriate way.

{

"Type": "bind",

"Source": "/opt/spotfire/nodemanager/14.0.6/nm/logs",

"Destination": "/logs",

"Mode": "rw",

"RW": true,

"Propagation": "rprivate"

}
