extend dump plugin to support resolving revisions

Browse Source 
This patch adds a flag --resolve-refs to the dump plugin.
Once enabled, all relative refspecs (e.g. branch or tag names) are
resolved and replaced by their exact revision (before patches are
applied).
When re-running kas on the flattened and expanded config file, the build
is executed against exactly the versions of the dependencies that where
used when dumping the configuration. This helps to keep track of build
versions for future use (e.g. reproducible builds) or for
version-tracking tools like renovate.
