Currently clio is encoding git commit hash for debug builds only.
Having the commit hash for release does not hurt anyone but has an added benefit - it allows us to know which exact code is used while going thru performance testing and/or running integration tests. Multiple times already we had a custom build installed on a server for perf/integration testing and we had no way to prove which code it's build from other than hoping that we did not copy/install the wrong thing.

Plan of attack:

• Talk to @legleux to find out if there are objections
• See src/main/impl/Build.cpp
• Version must always include the git commit hash. for both release and debug builds
• Make sure server_info shows the version string with the commit hash for debug and release.
