    Only consider tags that look like versions.

    pbr has been allowing any tag (e.g. 'fred') to be a version - but fred
    is clearly not a version! Since git describe cannot validate versions
    for us today, we need to perform the describe calculations ourselves.

    In order for this to work on Python3, a missing method __hash__ needed
    to be added to SemanticVersion.
