UI watch mode that automatically opens/updates panels from external IDE

[mofojed]

As a developer using an external IDE (such as VSCode or IntelliJ) in my workflow, I would like a browser mode that automatically opens/updates/closes panels as code is run in a session. I do not the Console, Command History, Log, etc. as those are all in my IDE already.

Desired workflow:

1. Set up IntelliJ to use a venv with deephaven and deephaven_server installed a. Create venv locally - python -m venv .venv b. Under File -> Project Structure -> Platform Settings -> SDKs, selection Python Home Path to be .venv/bin/python
2. Open up the Python Console and start a server:

from deephaven_server import Server
s = Server(port=10500, jvm_args=["-DAuthHandlers=io.deephaven.auth.AnonymousAuthenticationHandler"])
s.start()

3. Open a browser to http://localhost:10500/watch (whatever the URL should be ... /watch? /live?). Should be an app with an empty layout (settings accessible etc).
4. From a Python file in IntelliJ, enter some basic code, then right click and select "Run File in Python Console", e.g.

from deephaven import empty_table
t = empty_table(100).update("x=i")

5. The table should open up in the browser
6. Change the code in your file and re-run:

from deephaven import empty_table
t = empty_table(100).update("x=i*2")
t2 = t.update("y=x*i")

7. The browser should update with the newly created t2, and t should update to show the new value entered.
