We keep refrences to locator::token_metadata in many places.
Most of them are for read-only access and only a few want
to modify the token_metadata.
Recently, in 94995acedb,
we added yielding loops that access token_metadata in order
to avoid cpu stalls. To make that possible we need to make
sure they token_metadata object they are traversing won't change
mid-loop.
This series is a first step in ensuring the serialization of
updates to shared token metadata to reading it.
Test: unit(dev)
Dtest: bootstrap_test:TestBootstrap.start_stop_test{,_node}, update_cluster_layout_tests.py -a next-gating(dev)
