test: allow controlling etcd log level

Browse Source 
When running an integration test that measures performance, like for example
test/integration/scheduler_perf, running etcd with debug level output is
undesirable because it creates additional load on the system and isn't
realistic.

The default is still "debug", but ETCD_LOGLEVEL=warn can be used to override
that.
