Fix AWS EC2 inventory plugin caching of groups (#46961)

Browse source 
* Fix AWS EC2 inventory plugin caching of groups

* Added changelog fragment for aws_ec2 caching fix

* Store the AWS query results

The underlying inventory object contains inventory from other sources,
so caching it as ours would be wrong.
It seems easiest and safest to just cache the boto query results
instead.

* Remove unused functions
