Java : Fail to parse IPv6 address and port from bootstrap address in GcsClientOptions

[irshadcc]

What happened + What you expected to happen

In GcsClientOptions, ray tries to parse the bootstrap address, if the bootstrap address is IPv6 the condition check will fail even though the address is valid.

String[] ipAndPort = rayConfig.getBootstrapAddress().split(":");
Preconditions.checkArgument(ipAndPort.length == 2, "Invalid bootstrap address.");

The expected behavior should not throw IllegalArgumentException.

Versions / Dependencies

Latest

Reproduction script

These issue can be easily reproduced by setting the bootstrap address to IPv6 when using Java worker.

@irshadcc Hi, Ray on IPV6 network is a new and interesting scenario for us. I can fix this point to adopt ipv6 address, but i'm not sure if there are other block point because we don't have ipv6 network to verify it. Do you have any thought of this? Can you verify it quickly by the Ray source code after we commit?

[irshadcc]

Let me set up a test cluster to reproduce and fix. I will submit a PR after fixing it.

Sounds good!
