Title: [WIP] Report service version via "--version" flag

Now all the services report version when ran with --version flag.

Note: Version string in `st2common/st2common/__init__.py` file needs to be manually updated. I was thinking that we could and probably also should use this is an authoritative file for determining StackStorm version (during build process, in the docs, etc.).
