This pull request updates the scheduled e2e workflows and the ovs-ovn daemonset upgrade process. It removes the outdated release-1.10 branch from the tests and adds the release-1.12 branch to the upgrade tests. It also introduces a new post-upgrade hook for the ovs-ovn daemonset that uses a dedicated service account.

No more mercy for the old release
We cut it off from the e2e tests
We unleash the power of the daemonset
With the post-upgrade hook of ovs-ovn

• Remove the release-1.10 branch from the scheduled e2e workflow and the e2e upgrade tests for all scenarios (link, link, link, link, link, link, link, link, link, link, link, link). This is because the release-1.10 branch is no longer maintained and does not need to run the e2e tests periodically or be tested for upgrade compatibility.
