[lens] Datatable visualization and visualization switcher

[wylieconlon]

Summary

This PR is currently doing two things that are somewhat related, but could be split, so this is a draft for now.

The two things are:

1. Building out a data table visualization that works with the aggregations we have
2. Fixing some of the chart switching behavior

Related to the chart switching behavior is also generating better suggestions for alternative queries to run.

Summarize your PR. If it involves visual changes include a screenshot or gif.

You've probably already seen this, but the xy chart layouting has some problems

EDIT: This also happens on feature/lens, investigating...

I'm probably going to split up this PR into two or three smaller PRs that should be reviewable in sequence.
