Infrastructure refactor & new section

[rstegg]

Infrastructure's processes section needs a little bit of cleanup IMO, and possibly adding a new section, Coordination.

[01 - processes]

• Pull out Coordinating Teams
• Pull out Maintaining Project Focus

[04 - coordination]

• add Coordinationg Teams
• add Maintaining Project Focus
• add Team Collaboration? - Slack, Gitter

Thoughts?

Sounds good! I’m a bit unsure about the last two: do you have any examples of open source projects using mentioned tools except Slack?

[rstegg]

Nope you're right, I'll update it

@sapegin Hello, I would like to translate to Spanish but I do not know how. I would like to do it by means of pull request :)

@shadowz10 It's a bit too early as we have to finalize the book. I set up #79 for tracking.
