mini-cluster: disallow restarting daemons from other threads
If we restart an external daemon from a separate thread, the daemon can be
killed silently and without warning when the thread is reaped.
For instance, the following would fail without logging any information about
the tserver dying:
TEST_F(ExternalMiniClusterITestBase, TestRestartFromThread) {
ExternalMiniClusterOptions opts;
opts.num_tablet_servers = 1;
NO_FATALS(StartClusterWithOpts(std::move(opts)));
thread t([&] {
auto* ts = cluster_->tablet_server(0);
ts->Shutdown();
return ts->Restart();
});
t.join();
SleepFor(MonoDelta::FromSeconds(1));
ASSERT_TRUE(cluster_->tablet_server(0)->IsProcessAlive());
}
I didn't add a death test, since death tests themselves don't work well in
multithreaded contexts.
