Missing functionality - map.set_ttl

[mdumandag]

It seems that map proxy has a missing functionality: set_ttl. It should be trivial to implement this.

• We just need to generate codecs using the old protocol branch (https://github.com/hazelcast/hazelcast-client-protocol/tree/1.8.z) and copy the map_set_ttl_codec to the protocol directory.
• Implement the functionality (should be very similar to this https://github.com/hazelcast/hazelcast/blob/3.12.z/hazelcast-client/src/main/java/com/hazelcast/client/proxy/ClientMapProxy.java#L1425)
• Add documentation and tests
