    Move per role Services defaults into environment file

    For parameter merge strategies to work we need to merge multiple environment
    files, which doesn't consider the defaults defined in the heat template.

    Moving where we define these defaults will enable the merge strategies
    applied when appending services to roles in environment files to work.
