Apparently we used to set `loglevel debug` for tls in spawn_instance.
I.e. cluster and sentinel tests used to run with debug logging, only when tls mode was enabled.
this was probably a leftover from when creating the tls mode tests.
it cause a new test created for #11214 to fail in tls mode.
At the same time, in order to better distinguish the tests, change the
name of `test-centos7-tls` to `test-centos7-tls-module`, change the name
of `test-centos7-tls-no-tls` to `test-centos7-tls-module-no-tls`.
Note that in `test-centos7-tls-module`, we did not pass `--tls-module`
in sentinel test because it is not supported, see 4faddf1, added in #9320.
So only `test-ubuntu-tls` fails in daily CI.
