[DON'T MERGE] PoC of recording stats during kedro run

[noklam]

Description

#662

If you run

cd demo_project
kedro run

You should see a stats.json created.

Development notes

Pros:

• No extra cost to read data when users fire up viz to see the statistics.
• Need better way to manage the version, or maybe it is ok because the current pipeline view also only display the latest pipeline. If viz saw this file then it can optionally skip the read.

Cons:

• It can only show the stats for the last run, if it's the first time user fire up Viz it won't work.
• Requires an upgrade of kedro-viz & a new kedro run to generate this stats.json

Notes:
It's a PoC, if we actually want to implement this we need to be more careful about the type checking, maybe we can check the type of the dataset instead of data. We may also need to take care of the remote storage (or it could be a next step)
