Allow to use --proxy on cron job

[shogondo]

Hi,

I faced a problem that I cannot use --proxy option on cron job with 'Too many arguments.' error.

Currently, /etc/cron.d/codedeploy-agent-update is defined as follows:

# Cron that starts once every day or on reboot, which updates codedeploy-agent.
# This cron file has been fuzzed to run after 04:45:05 every hour.
45 4 * * * root /bin/sleep 5; /opt/codedeploy-agent/bin/update --sanity-check --upgrade rpm
15 * * * * root /bin/sleep 5; /opt/codedeploy-agent/bin/update --sanity-check --downgrade rpm
@reboot root /bin/sleep 45; /opt/codedeploy-agent/bin/update --sanity-check rpm

According to https://github.com/aws/aws-codedeploy-agent/blob/master/bin/update#L135, update script can be passed up to 4 arguments. So I cannot set proxy like 45 4 * * * root /bin/sleep 5; /opt/codedeploy-agent/bin/update --sanity-check --upgrade --proxy http://x.x.x.x:yyy rpm.

@shoutakenaka can you add some tests for this change?

@rohkat-aws I cannot find test/spec/feature for bin/update. Is there no automated tests of this script for now?
