Improve version check error message
-
_support/test-boot checks that 'gitaly -version' reports the correct version denoted by the VERSION file. If the versions mismatch, the error message currently just says 'gitaly -version failed'. This is not very helpful so this commit improves the situation by actually printing out the expected and actual content.
One potential source of failure is when a merge request is made from a fork that does not contain the latest tags, causing
git describe
to produce different output. This commit also adds a message about this to help community contributors working from forks.
