Version 12.1 backport

[berland]

Backports:

• Compatibility with everest-models 1.3.1 (bugfix compared to 1.3.0)
• Workaround Python bug for shutil.copytree() exceptions
• Avoid repeated logging for each cluster in misfit analysis
• Avoid deprecated utcnow()

• PR title captures the intent of the changes, and is fitting for release notes.
• Added appropriate release note label
• Commit history is consistent and clean, in line with the contribution guidelines.
• Make sure unit tests pass locally after every commit (git rebase -i main --exec 'pytest tests/ert/unit_tests -n logical -m "not integration_test"')

When applicable

• When there are user facing changes: Updated documentation
• New behavior or changes to existing untested code: Ensured that unit tests are added (See Ground Rules).
• Large PR: Prepare changes in small commits for more convenient review
• Bug fix: Add regression test for the bug
• Bug fix: Create Backport PR to latest release
