Update noresm_develop with new blom tag dev1.6.1.10

[TomasTorsvik]

I would like to update noresm_develop with the new blom tag dev1.6.1.10. How is this done when using the git fleximod system?

I see that I should update the .gitmodules file, but should I also do something in the components directory?

Updating a NorESM component tag has two goals:

• Commit NorESM (top level) so that all component submodules are recorded in the desired state. That is, running git checkout --recurse-submodules <new_tag> at the top level should checkout the NorESM tree to the correct state.
• Document the correct tag(s) by updating the fxtag entries in the top-level .gitmodules file

I think this is procedure should always work:

1. In your NorESM clone, create a new update-BLOM-tag branch and fully check it out (git checkout -b update-blom-tag NorESM/noresm_develop && ./bin/git-fleximod update --optional).
   • git submodule status should be 'clean' (the first column is blank for all submodules).
2. In components/blom, checkout the new tag and run git submodule update.
   • git submodule status should be clean.
3. At the top level, update the fxtag value in the blom submodule section of the .gitmodules file with the new BLOM tag.
4. Run git commit -a -m 'Updated BLOM tag to rev.x.y.z.q'.
5. Push this to your fork and open a PR.

Also, would it be possible make BLOM tags annotated? dev1.6.1.5 is but the others in the dev1.6.1 series are not.

@gold2718 - Thanks for the procedure. I will copy this into the git-fleximod discussion #599 for later reference.

I was not mindful about the difference between lightweight and annotated tags. It would seem that tags created via the gitHub interface are always lightweight. So annotated tags should be created outside gitHub and be pushed to the repository, before creating the release. Is this procedure documented somewhere?

I have removed the previous tag and created a new annotated dev1.6.1.10 tag.

I found a bug during testing. This will be addressed with an update on BLOM, followed by a new tag. The BLOM update should target noresm2_5_alpha09, so I will wait with making a new PR until all bug fixes for alpha08 have been merged.
