Description

Right now

private IOStreamPair checkTrustAndSend(InetAddress addr,
OutputStream underlyingOut, InputStream underlyingIn,
DataEncryptionKeyFactory encryptionKeyFactory,
Token<BlockTokenIdentifier> accessToken, DatanodeID datanodeId)

only provide an API without secretKey paramter for 

checkTrustAndSend(
InetAddress addr, OutputStream underlyingOut, InputStream underlyingIn,
DataEncryptionKeyFactory encryptionKeyFactory,
Token<BlockTokenIdentifier> accessToken, DatanodeID datanodeId,
SecretKey secretKey)

Remove the former API to make it cleaner
