crypto: warn if counter mode used in createCipher

`crypto.createCipher()` sets the fixed IV derived from password and it
leads to a security risk of nonce reuse when counter mode is used.
A warning is emitted when CTR, GCM or CCM is used in
`crypto.createCipher()` to notify users to avoid nonce reuse.
