Core Introduction review

Hi Ulf,

I took an action to review Core spec's Introduction for this week's
call.

https://raw.githack.com/w3c/automotive/gh-pages/spec/Gen2_Core.html#introduction

Together on call we can discuss what needs to be included in
introduction to explain what this is at a high level yet remain
succinct.

What I think we need to cover in the introduction: 

* Explain what 'Gen2' is, service for accessing vehicle signals (and
potentially other data models)
* Where it is likely to be deployed - in-vehicle and indirect against
data in cloud
* Identify it as a successor to VISS, what it adds in brief (REST,
security...)
* Need a name soon and stop calling it Gen2, deferred earlier

interested in others' opinions.

Then include the distinction between Core and Transport you have and
finally a bit more on Core. The same intro can be used for both
documents with the last paragraph or so focused on Core and Transport
respectively.

I can take a pass on wording after we agree on broad points.
