[cloud] Remove repeated error handling and region checking, both now in boto3_conn (#32774)

* Remove boto usage from boto3 modules

* Remove region checking

boto3_conn now takes care of region checking and handles NoRegionError
exceptions with a standard message

boto3_conn also takes care of other connection exceptions too.

* Document boto3 as a requirement for ec2_eni_facts
