<service>_git_install_branch is ignored if placed in group/host_vars

[Dmitriy Rabotyagov]

In case you want to override some service version specificaly for some group or some individual host you would try to define <service>_git_install_branch in group/host_vars

However, play vars_files have prescedence over inventory group_vars [1], so the only way for override is usage of user_variables, which does not give enough flexability for some cases.

    Move repo_packages to group_vars

    At the moment it's not possible to apply different versions of
    services to the different groups due to playbook vars having
    prescedence over group_vars. However, it can be quite important
    to such use cases, for example for phased rollouts of newer versions.

    This will also reduce amount of unnecessary variables that are included
    for each host, since only required git details will be loaded.
