* Split mistral components list from other repo of the project, this
will help beginners understand what is really started when mistral
starts
* Stop giving too much info on how to start components. Only one exemple
when you start all and some components is enough
* Stop explaining stuff about fake transport_url driver, this is useless
and wrong (the inprocess memory is true, but since mistral is starting
multiple workers outside of unit tests, it does not present any value
to explain that in the install guide)
