`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.

The previous commit is a back-port of pull request nodejs#13821 to v6.x. Its regression test does not apply to the v6.x branch (depends on semver-major pull request nodejs#9405) so this commit adds a new test. Refs: nodejs#13821 Refs: nodejs#9405
EVP_CIPHER_CTX_FLAG_WRAP_ALLOW flag needs to be set in using wrap mode ciphers. In `crypto.createCipher()`, AES key wrap mode does not use a default IV defined in RFC3394 but a generated IV with `EVP_BytesToKey()` to be consistent API behaviors with other ciphers. The built-in AES wrap mode in OpenSSL is not supported in FIPS mode as http://openssl.6102.n7.nabble.com/AES-Key-Wrap-in-FIPS-Mode-td50238.html so its tests in FIPS mode are skipped.
