Release 0.11.0

[Lorak-mmk]

This PR is to review the changes required to release new version. It should NOT be merged, so I opened it as a draft.
After the approve, I will perform following steps (correct me if I'm wrong @piodul):

• git checkout branch-0.11.x
• git tag -a v0.11.0
• git push origin v0.11.0
• git checkout main
• git merge --ff-only branch-0.11.x
• git push origin main
• Check that documentation was built and published successfully
• Create a github release with previously approved release notes
• Push new version to crates.io:
• Create post on the forum about release

Pre-review checklist

• I have split my patch into logically separate commits.
• All commit messages clearly explain what they change and why.
• I added relevant tests for new features and bug fixes.
• All commits compile, pass static checks and pass test.
• PR description sums up the changes and reasons why they should be introduced.
• I have provided docstrings for the public items that I want to introduce.
• I have adjusted the documentation in ./docs/source/.
• I added appropriate Fixes: annotations to PR description.

CI fails because:

1. I didn't update Cargo.lock.msrv - will fix it in a moment
2. Some issue with Sphinx theme. Opened and issue about it here: sphinx-scylladb-theme 1.6.4: No module named 'importlib_metadata' sphinx-scylladb-theme#966

[Lorak-mmk]

Fixed the Cargo.lock issue. Now the only release blocker is the sphinx theme issue :(

The commits and the procedure looks good. Before giving approval, I'll wait until the docs issue is fixed and we get a green light on all jobs.

The docs issue was fixed. Approving.
