Need to update the build scripts to set the version as a global veriable to do this properly. Will have a PR tomorrow printing this out once I get acclimated to the build process.

https://github.com/ansibleplaybookbundle/ansible-playbook-bundle/pull/219

Didn't have to mess with the build scripts to get this working thankfully.

You can now do `apb version` and it will print out the current version.

1, RPM installation:
[root@localhost jzhang]# rpm -qa|grep apb
apb-1.1.7-1.20180202175805.el7.centos.noarch
[root@localhost jzhang]# apb --help
usage: apb [-h] [--debug] [--project BASE_PATH]
           {relist,run,help,test,prepare,setup,bootstrap,list,remove,init,version,build,push,serviceinstance}
           ...

APB tooling for assisting in building and packaging APBs.

optional arguments:
  -h, --help            show this help message and exit
  --debug               Enable debug output
  --project BASE_PATH, -p BASE_PATH
                        Specify a path to your project. Defaults to CWD.

subcommand:
  {relist,run,help,test,prepare,setup,bootstrap,list,remove,init,version,build,push,serviceinstance}
    relist              Relist the APBs available within the Service Catalog
    run                 Run APB
    help                Display this help message
    test                Test the APB
    prepare             Prepare an ansible-container project for APB packaging
    setup               Initialize OpenShift with APB development environment
    bootstrap           Tell Ansible Service Broker to reload APBs from the
                        container repository
    list                List APBs from the target Ansible Service Broker
    remove              Remove APBs from the target Ansible Service Broker
    init                Initialize the directory for APB development
    version             Get current version of APB tool
    build               Build and package APB container
    push                Push local APB spec to an Ansible Service Broker
    serviceinstance     Create a ServiceInstance template based on apb.yaml

[root@localhost jzhang]# apb version
Version: apb-1.1.7
