gerrit-etc branches and documentation

[Bjoern Michaelsen]

Hi there,

There are a few patches waiting on gerrit about gerrits configuration itself:

 https://gerrit.libreoffice.org/#/q/status:open+project:gerrit-etc,n,z

Now the gerrit-etc project has some specific branch setup that I dont
understand, with a prod and a master branch and some patches on each that are
not on the other AFAIK. 

@Norbert, David: Can you please set up a wiki page describing the recommended
way to get things in there? Or alternatively, put a big fat "README" file in
the root of the repo doing that? Thanks.

Best,

Bjoern
