Heat docker plugin unable to start containers on latest Docker

[Daniel Park]

Recent versions of Docker no longer seem to support parameters when starting a container.

Thus the Heat docker plugin will cause the following error to occur:
starting container with non-empty request body was deprecated since v1.10 and removed in v1.12"

Where problem is occurring:

Example template to use:
