Web console: revamp the experimental explore view

[vogievetsky]

This PR changed Explore view to be able to work on top of an arbitrary query as its "source" instead of just a table.

To achieve this I needed to get rid of @druid-toolkit/visuals-core and @druid-toolkit/visuals-react and reimplement a lot of the logic. That (and also the fixed to the test for the grouping table) account for the majority of the changes.

With this PR the explore view can:

be configured on top of a "source" query

make edits to the source query via point-and-click

store "Measures" in the source query

Have stateful URLs

This PR also fixes misc bugs in the explore view (and probably creates a greater number of new ones due to the increased surface area).

this is an amazing tool, kudos 🤘

its like all the beauty and speed of exploration provided by a data visualization tool with all of the power and control of writing raw SQL when you need it, this can do so very much, i'm incredibly impressed 🎉

clicked around for a long time and found a few issues (see you've pushed a couple commits since i pulled so idk if any of these are already fixed):

• changing time granularity doesnt refresh chart in time chart view
• browser back does not refresh chart (but does go back, if i refresh page it shows the previous thing)
• deleting max rows sets to 0 which makes a query that fails (maybe druid could do better here too)
• if you dont select __time in the base query, lots of stuff that works by issuing queries on time stops working
• filters seem like they get created incorrectly for array columns, e.g. WHERE "arrayDouble" = '[1.1,2.2,3.3]' should be something like WHERE "arrayDouble" = ARRAY[1.1,2.2,3.3]
• multi-axis chart layout seems to get a bit wonky if adding too many measures
• dev tools open in chrome wreaks havoc on chart tooltip info popup thingy

I don't think these all need to be resolved before merging, though the back button one might be nice. I also feel like this is cool enough now that maybe we should consider putting it on the top bar instead of hidden behind the '...' to get it more exposure, but that discussion also doesn't need to block merging.

I had so much fun clicking around various things I found a druid bug, #17183, the 0 limit thing might also be something to improve, haven't looked at that yet

Thank you so much for the review and the positive feedback!

changing time granularity doesnt refresh chart in time chart view

Can't repro this, is it possible your datasource was already floored to hour (query granularity) and you were changing between say 5min and 1hr?

browser back does not refresh chart (but does go back, if i refresh page it shows the previous thing)

Fixed, made back and forward work as expected

deleting max rows sets to 0 which makes a query that fails (maybe druid could do better here too)

Fixed, it was not listening to it's min of 1

if you dont select __time in the base query, lots of stuff that works by issuing queries on time stops working

Partially fixed by making things more robust and show errors better. Some things will still not work without a TIMESTAMP column but at least they will tell you about it

filters seem like they get created incorrectly for array columns, e.g. WHERE "arrayDouble" = '[1.1,2.2,3.3]' should be something like WHERE "arrayDouble" = ARRAY[1.1,2.2,3.3]

Yeah, this is also a bug in the query view. I will fix it in a followup PR. Would be cool to make an ARRAY filter UX also

multi-axis chart layout seems to get a bit wonky if adding too many measures

Yup. skipping this for now but will look into it in a followup

dev tools open in chrome wreaks havoc on chart tooltip info popup thingy

Can't repro this either but not super concerning if devtools need to be open (it might be some mode that you have set, like touch mode). Will followup offline.
