/**
* The AWSConfig contains the configuration for AWS join mechanism.
*
* what happens behind the scenes is that data about the running AWS instances in a specific region are downloaded using the
* accesskey/secretkey and are potential Hazelcast members.
*
Filtering
* There are 2 mechanisms for filtering out AWS instances and these mechanisms can be combined (AND).
*
* - If a securityGroup is configured, only instances within that security group are selected.
* - If a tag key/value is set, only instances with that tag key/value will be selected.
*
* Once Hazelcast has figured out which instances are available, it will use the private IP addresses of these
* instances to create a TCP/IP-cluster.
