Merge behaviour

Replace or Merge dictionaries (with "hash_behaviour=replace" in ansible.cfg):

# Replace             # Merge
---                   ---
  vars:                 vars:
    dict:                 merge:
      a: "value"            dict: 
      b: "value"              a: "value" 
                              b: "value"

# How does merge work?:
Your vars [host_vars]  -->  default vars [current role] --> default vars [include role]
  
  dict:          dict:              dict:
    a: "1" -->     a: "1"    -->      a: "1"
                   b: "2"    -->      b: "2"
                                      c: "3"
