xdg-open errors when publishing content

[scubastevew]

Using the rsconnect-python package to publish content in rstudio.cloud, these xdg-open errors are displayed in the terminal, even though the content is published correctly.

xdg-open: no method available for opening '<URL>'

Steps to Reproduce:

1. Publish python content using the rsconnect-python package in rstudio.cloud

Expected Results:

1. Content is published without the xdg-open errors.

From rsconnect in R, we have a launch.browser argument to rsconnect::deployApp that is disabled when interactive and can be used to configure / prohibit launching a browser:

That gets threaded into openURL:

We probably need something similar.

@aronatkins I don't think that's what we need (though it would probably be useful in some cases). rsconnect is able to open URLs through utils::browseURL through what seems to be a monkey-patched implementation. Ideally we'd have the same thing for Python, but we could potentially settle for skipping the webbrowser.open_new call in cloud if that's not feasible.

[aronatkins]

@mslynch Sorry that I wasn't clear -- I was giving references to prior work on the R side - where we allow R options and function arguments to control if and how a URL is opened after the deploy completes.

I'm not sure how rstudio.cloud adjusts the browser-open call for R deploys; you might be able to allow something similar here.
