Harshavardhana 99bf4d0c42 [sec] Match ${aws:username} exactly instead of prefix match (#7791)
This PR fixes a security issue where an IAM user based
on his policy is granted more privileges than restricted
by the users IAM policy.

This is due to an issue of prefix based Matcher() function
which was incorrectly matching prefix based on resource
prefixes instead of exact match.
