SERVER-32907 Reduce replication.heartbeat log verbosity in local test logs

This patch creates separate 'logComponentVerbosity' default settings
for tests running running locally versus those running in
Evergreen. This only applies to tests run using resmoke.py. We detect
that a test is running in Evergreen by checking if resmoke received
an EVERGREEN_TASK_ID parameter.
