    [security] 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

     * excluding the general "*" pattern which matches all bots.
     *
     * @param userAgent the user agent string to match against directives,
     *                 can be null (treated as empty string)
     * @return the most specific matching directive, or null if no directive matches
     */
    public Directive getMatchedDirective(final String userAgent) {

                // Check field name follows convention
                assertTrue("Field name should match pattern: " + field.getName(), labelPattern.matcher(field.getName()).matches());

                // Check field value follows convention
                field.setAccessible(true);
                String value = (String) field.get(null);
