Remove_volume_tags

[herman-wong-cf]

• Set ebs_optimized to "true" according to Checkov recommendations.
• Per Terraform docs for "aws_instance" resource, setting "volume_tags" when "aws_ebs_volume" is being used to also define tags will cause a perpetual diff when reapplying. volume_tags is removed to avoid this problem.

Talked though with team this is good with me. Will communicate to parties and create a new major release
