### Motivation
When a broker shutdown or gets killed, the leader broker will get notified
and soon reassign the orphan bundle ownerships. Meanwhile, the ownership lookup
to these orphan bundles should be deferred til the new brokers own them. This
will further reduce the lookup request retries when brokers are shutdown or get
killed.
### Modifications
- In `ServiceUnitStateChannelImpl.getOwnerAsync`, additionally, check if the
current owner broker is active or not in the broker registry. If active, return
the current owner. Otherwise, defer the ownership lookup requests til the new
owner owns it.
- During the orphan ownership cleanup, when there is no selected owner, the
leader overrides the orphan states to `Free`.
- Do not throw exception from `writeLoadReportOnZookeeper`
`writeResourceQuotasToZooKeeper`

<!--
After opening this PR, the build in apache/pulsar will fail and instructions
will
be provided for opening a PR in the PR author's forked repository.
apache/pulsar pull requests should be first tested in your own fork since
the
apache/pulsar CI based on GitHub Actions has constrained resources and quota.
GitHub Actions provides separate quota for pull requests that are executed
in
a forked repository.
The tests will be run in the forked repository until all PR review comments
have
been handled, the tests pass and the PR is approved by a reviewer.
