Use UUID for auto-generated jvmRoute

Currently, auto-generated jvm-routes are of the form: bind-address:port:engine-name
This exposes internal addresses/ports and is not appropriate for production systems.
To fix that, we can use UUIDs.
e.g.

InetAddress connectorAddress;
int connectorPort;
String engineName;

int addressBytes = connectorAddress.getAddress().length;
int intBytes = Integer.SIZE / Byte.SIZE;
int charBytes = Character.SIZE / Byte.SIZE;

ByteBuffer buffer = ByteBuffer.allocate(addressBytes + intBytes + (engineName.length() * charBytes));
buffer.put(connectorAddress.getAddress());
buffer.putInt(connectorPort);
buffer.asCharBuffer().put(engine);

String jvmRoute = UUID.nameUUIDFromBytes(buffer.array()).toString();

I can think of 2 disadvantages:
1. UUID jvm-routes will be, on average, longer than the current default, i.e. 36 characters as opposed to ~28. Not a significant difference there.
2. For development, exposing the address and port via the jvm route might be useful. To satisfy this requirement, we can make the use of UUIDs configurable.
