Setup .gitconfig file for unilog via Puppet

[iperdomo]

We need to have a $HOME/.gitconfig file for the user running the unilog JVM process in order to avoid problems when trying to execute git clone git pull.

We experienced a downtime in unilog live server because of this:

git pull

*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

fatal: empty ident  <unilog@live9.live.akvo-ops.org> not allowed
