just to make sure - this is a list of list of dictionaries.
If this is your source of truth, and you intend to have a list of dicts,
then it could look like this:
domain_definition:
- name: server11
cluster: cluster1
port: '8080'
- name: server12
cluster: cluster2
port: '8090'
- name: server21
cluster: cluster3
port: '9080'
- name: server22
cluster: cluster4
port: '9090'
This will make a difference when manipulating the data.
