Describe the bug
Dora remote connection has been long awaited. We however need to fix a couple of things to make it work:

Tracking issue

• Make hard-coded localhost address configurable in the daemon and the coordinator
• Make working_dir configurable dependent on the machine on multi daemon situation.

Update

Additional Tracking issue

• Make CLI coordinator connection configurable.

Currently the CLI can only connect to the local preconfigured coordinator. We should make it configurable such as:

dora start dataflow.yaml --coordinator-addr IP:PORT

• Make working_dir configurable dependent on the machine on multi daemon situation.
