[logdog] Stream view explicitly cancels request.

Currently, a request, when cancelled, is ignored, but is still alllowed
to proceed. This causes HTTP requests for logs that are cancelled to
actually cancel their underlying requests.

[logdog] Replace list view with query view.

The list view is near-useless, as the log stream space is too large to
effectively navigate through list clicks. Replace it with a query view.

This query view is fairly simple at the moment. The intent is to improve
it over time.

[logdog] Remove list functionality.

LogDog has grown too large for this to be useful. List has been replaced
in the UI with Query, which is superior for all practical purposes. Now,
remove List entirely to reduce code burden.

Oops, we were actually using this. :(

https://cs.chromium.org/chromium/src/tools/accessibility/rebase_dump_accessibility_tree_test.py?q=%22cit+logdog+ls%22&l=123

Can we achieve the same thing using "query"?

Looks like this is the root of issue 760245
We use this in src/tools/accessibility/rebase_dump_accessibility_tree_test.py
Is there an alternative query command we can use?

We are working on a solution with query.
