fix: s3 command ignore -tlsVerifyClientCert and -cacert.file arguments (#6547)

s3 command ignore tlsVerifyClientCert and cacert.file arguments from
command line. On startS3Server instead of use real values (in s3opt),
default values (from s3Options, always empty) are checked.

Now on right values are checked and if user provide this arguments
RequireAndVerifyClientCert is set and/or ca certificate is loaded.
