> From offline discussion with [~asuresh], if an AM tries to promote or increase a container
whose enforceExecutionType is set to false, the scheduler may, in the presence of oversubscription,
 allocate an OPPORTUNISTIC container. This should not happen given the contract we have in
container update API.
