Improving container startup time for Docker

When creating the base docker image, the runtime .zip file is extracted before the BWEngine starts, causing a delay in the container startup time.

To avoid the delay, use the modified Dockerfile setup.sh, and the start.sh scripts to extract the TIBCO BusinessWorks Container Edition runtime .zip while creating the base image.

The reducedStartupTime folder contains the modified Dockerfile, the setup.sh script, and the start.sh script.

Replace the Dockerfile from TIBCO_HOME/bwce/<version>/docker and both the setup.sh and start.sh scripts from TIBCO_HOME/bwce/<version>/docker/scripts with the Dockerfile and the setup.sh and start.sh scripts placed inside thereducedStartupTime folder.
