Get a bad gateway when try to install plugin.

[lowks]

This is the output when I try to run sensu-install -p aws :

[root@ip-172-31-6-16 centos]# sensu-install -v -p aws

i believe the issue here is the huge number of dependencies. the installation hangs for me for about 5-10 minutes at the point you ctrl-c'd--but eventually completes.

replicating the issue here is as simple as gem install -V sensu-plugins-aws without any of the deps installed. i recommend you prepare a sandwich ahead of time.

yes this is the same issue really as #293 some work is underway but we really need to get people that use the various scripts in there to test using only aws-sdk-v3 and the required gems rather than pulling in everything.

I have seen that adding more resources to a machine has a significant impact on this.
