cloudwatch metrics can be turned off

Add the Lambdakiq.config.send_cloud_watch_metrics variable to deactivate the cloudwatch events. CloudWatch events are activated by default.

Hi @jeremiahlukus ,
I guess this PR was closed because it is not useful. How can I stop sending metrics to CloudWatch without this PR?
I tried adding this to the config/application.rb file, but I still receive a lot of Cloud Watch metrics:

config.lambdakiq.metrics_logger = Logger.new("/dev/null")

Those Cloud Watch metrics have a huge impact on billing at scale.

Honestly thought it was stale or no longer needed. I’ll reopen and take a look at it
