Annotations support for FusionAuth ServiceAccount

[ladogolijashvili]

Is your feature request related to a problem? Please describe.
We want to communicate with Elasticsearch with EKS ServiceAccount throught IAM roles, for that serviceaccount must have annotations about IAM role it must assume, right now chart is only creating ServiceAccount but there is no possibility to add annotations. I can add feature but as i see in README history, this repo is no longer maintained by community.

Describe alternatives you've considered
We are deploying helm with terraform so creating serviceaccount and rolebindings outside helm chart is possible but as helm is controlling deployment pods wont be available to use terraform created serviceaccount
