This log allows us to easily distinguish between full coverage and
minority partition when the cluster fails. Sometimes it is not easy
to see the minority partition in a healthy shards (both primary and
replicas).
And we decided not to add a cluster_fail_reason field to cluster info.
Given that there are only two reasons and both are well-known and if
we ended up adding more down the road we can add it in the furture.

We currently has two disjoint TCL frameworks:
1. Normal testing framework, which trigger by runtest, which individually
launches nodes for testing.
2. Cluster framework, which trigger by runtest-cluster, which pre-allocates
N nodes and uses them for testing large configurations.
The normal TCL testing framework is much more readily tested and is also
automatically run as part of the CI for new PRs. The runtest-cluster since
it runs very slowly (cannot be parallelized), it currently only runs in daily
CI, this results in some changes to the cluster not being exposed in PR CI
in time.
This PR migrate the Cluster mode tests to normal framework. Some cluster
tests are kept in runtest-cluster because of timing issues or not yet
supported, we can process them later.
