BUG: print_version_info() doesn't work outside of ria directory

[mrl280]

Description:
print_version_info() only works if your current working directory is the 'ria' directory.
If you are in a different git project, it will report the git hash of that project.
If you are not in a git project, the helper function _get_commit_hash() will raise a RunTimeError.

Project Area:
ria.diagnostics.print_version_info.py

Steps to Reproduce:
Run ria version from the command line outside the ria project directory, or ria.print_version_info() from within a Python environment.

Expected Behavior:
Report the git hash of the installed version of ria.

Actual Behavior:
Report the git hash of the current working directory, If you are in the 'ria' directory, it works as expected, but otherwise it scrapes the wrong hash. Raises a RunTimeError if you are not in a git directory.

I removed the broken implementation in fdb097d. Additional work is needed to develop a new implementation.
