doc: Mention contributor agreement immediately after Gerrit

I walked through the steps for a contribution but ended up
with an error when doing "git mail" because I didn't have a
signed agreement.

Added a section to check for or create one through Gerrit right
after the user has created the account and logged in.

Moved some info from copyright section to the new section.
