provision/docker/docker: created functions to generate deploy commands

There are two functions: one to run the deploy script in the
application's container and another one to run the application.
provision/docker/suite_test: added needed configurations to run a container in SetUpSuite
provision/docker/provisioner: passing function argument to generate cmds for container creation
