fetch tags from IMDS not from API

[durzo]

for some time now its been possible to get tags in the ec2 instance metadata service so you no longer need IAM credentials to query the API.

see: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/work-with-tags-in-IMDS.html

while this plugin has not been updated in years, it is (afaik) the only fluent plugin that provides aws ec2 metadata listed on https://www.fluentd.org/plugins

if this plugin is still being maintained, can we have this feature? are there any newer forks?
