Cipher suite conversion between Java and OpenSSL

Related: #3285

Motivation:

When a user attempts to switch from JdkSslContext to OpenSslContext, he
or she will see the initialization failure if he or she specified custom
cipher suites.

Modifications:

Provide a utility class that converts between Java cipher suite string
and OpenSSL cipher suite string

Result:

It is possible to convert all known cipher suite strings.
