Unused variables in unit tests

[kaylareopelle]

Running our full suite of Minitest tests reports that the following variables are declared but never used. Each test should be verified to see if the variable can be removed entirely or if the test should be refactored to include the use of the variable.

test/new_relic/agent/configuration/manager_test.rb:497: warning: assigned but unused variable - dd
test/new_relic/agent/configuration/manager_test.rb:515: warning: assigned but unused variable - dd
test/new_relic/agent/tracer_test.rb:311: warning: assigned but unused variable - segment
test/new_relic/dependency_detection_test.rb:214: warning: assigned but unused variable - executed
test/new_relic/dependency_detection_test.rb:231: warning: assigned but unused variable - executed
test/new_relic/dependency_detection_test.rb:248: warning: assigned but unused variable - executed

These warnings can be reproduced by running: bundle exec rake test
