daml-sdk-head: add optional sha information This PR add an option, `--sha`, to `daml-sdk-head` so that it produces a more accurate version number including the current git sha. The main consequence is that calling `daml-sdk-head --sha` take significantly longer than calling `daml-sdk-head`, because it needs to recompile everything that depends on the version number. > ## Wait, but why?? I started this work in support of an internal project that needed to test against unreleased, and possibly unmerged, daml versions. However, after further discussion I believe there is a better option for their use-case. I've decided to still open this PR because the work was done and there is no downside to it. It may still be useful if one wanted to be able to maintain more than one non-released local version of daml. CHANGELOG_BEGIN CHANGELOG_END
