Group throughput chart data by span action

[gggritso]

tl;dr

• the "Requests Per Minute" chart on the Requests landing page (and domain summary page?) should be split up by HTTP operation. i.e., 5 lines, for HTTP GET, HTTP POST, etc.
• the "Queries Per Minute" chart on the Queries landing page (and the queries summary page?) should be split by database operation. i.e., 5 lines for SELECT, INSERT, etc.

A few notes:

• we've gotten this request from a few people now, and it makes a lot of sense
• a "Top 5" chart also shows an "Other" category, so we don't need to worry about showing too many lines
• this should probably be a toggle, and maybe a filter, so people can select the exact action they're interested in
• if splitting up by all actions is too granular, we can split up by "theme" e.g., in Databases, read vs. write operations rather than every possible operation
