Summary-style status screen (1/2)

[olizilla]

ETA (April 2020):

This may be superseded by https://github.com/ipfs-shipyard/ipfs-webui/issues/1003 (dashboard-style revision of entire UI).

Original issue:

All three apps show IPFS node stats as part of the initial UI that is show the user first, at startup.

Let's identity which bits of information a useful to which users and under what circumstances. What background knowledge is needed to interpret the data. What unit should it be presented in? How frequently does the info change? Is it most useful as a current value, or is it best presented as the change over time of the value?

The current state of things is described here: https://github.com/ipfs-shipyard/pm-ipfs-gui/blob/master/research/README.md#ipfs-node-info
